I cut my guide bosses down on my vortecs with the comp cams tool, installed Z28 springs without the dampers, and have been driving it 8+ years with zero problems.
You can get .100 longer stainless valves cheap from erson, with longer hardened pushrods also to keep geometry correct . This avoids what may be expensive machine work to cut the guides down ! Hope this helps.
Dude! Why do you not have more VIEWS! This is an amazing video! You have a good clear way of explaining all of this and for the FIRST time, I understand lift - You have a new sub - I hope you can grow your channel!
Thanks man I really appreciate that! I have alot of cool projects on the go and finally decided to start filming some of it. There is alot of weird info out there so I'm trying to make videos that I wish i had a few years back when I needed info. Please share my videos and hit me up if you need any help or parts for your vortec projects!
@@cuttersperformance Thank you for sharing!!! I just did my first top end rebuilt on my 1970 chevelle crewcab. I used Vortec heads on the 307 bottom end. I have a 350 in the garage and I wanting to use my vortec heads on them with a nice cam - but I don't want to machine the hell out of them. With this information, I can get springs and put a nice cam in it and really go to town! Keep up the content - you actually explain things so that EVERYONE can understand. I am learning all of this and have been lost. There is a guy locally who I met on the SBC board on Facebook and he has been an awesome GURU for me as well! You are right there is not only so much misinformation but also nasty people who get hateful in a second if you don't grasp the concept they are poorly explaining. So, I tip my hat to you - and I will share your content with everyone I can.
I'm going to totally agree with this statement. And I have over 20 years experience building high performance engines, and so I also know what to look for when people make videos about a specific subject. I'm also the type that will call out somebody when they're just trying to get views but don't really know what they're talkin about. While there would be a couple of things I would add, this video is quite good and quite informative, and also explaining things in a clear way for others to understand. I can only imagine who gave it thumbs down. But then again it seems like every good video has thumbs down but nobody comments on why. Anyways this is a very misunderstood subject and very rarely do I see people cover it this clearly. I'm definitely impressed.
I agree that this is an excellent vid. The reason there aren't more views is because these engines are obsolete. LS is the budget build of choice now and the next generation LT has been out for quite awhile now. The LT will replace the LS and will only gain momentum in the coming years.
@@michaeldose2041 I understand what you are saying , but I'm soon to be 72 and I like the Vortec so I don't need all that wiring .I'll run a carb and hei , suits me fine .I don't race anymore .
Thank you for taking time to record this video. I finally understand how to determine maximum valve lift for my ZZ3 heads. You explained it in a way that makes sense.
I use the screw in studs too. A lot of the circle track rules say ya cant but those incognito ones have never been seen. I also break-in my motors on a run in stand before they go to the dyno with either a less than 80lb seat pressure spring or remove the inner spring.
@@cuttersperformanceI would love a PCP key chain!!! I have suggested (on many, many forums) to people who are doing vortec heads that they should look up PISS-CUTTER PERFORMANCE on UA-cam, now you changed your name... And can we get some new vids???
One thing to note, I did not see you cover in either video. I watched two of your video's on this topic you put out. You can run harden valve lash caps to get the needed stem height for the self aligning rocker arms. Just something to add I know a lot of people shy away from running them but they do work, also yes I know I am commenting on a 3 year old video just figured I would add this for those that did not know.
Someone mentioned to me that they had seen a UA-cam video about swapping to complete LS valve train. I don't remember, they said they were the 1.99" intakes and 1.55" exhaust. Upgrading to a bronze 1/2" odd guide for the .312" valve stem, as well as the LS6 springs. I haven't found anything on this. I've found plenty of videos, swapping springs. Yours is the most comprehensive on the spring swap. But I'm wondering if there is any advantage, performance-wise, flow-wise or weight-wise with that kind of swap. All I know is is from what I've been finding in researching, is that the stock 1.94s and 1.50s are pretty much better off left alone rather than going to a 2.02 and 1.60. Have you ever seen or heard about anything about the valve & spring swap (and guide) upgrade?
I've been looking everywhere for # 99095-1 keepers and they are OOS everywhere. I can find Howards 93010 keepers. They are a forged version with +.050 and seem to be a little cheaper.
@@cuttersperformance The Howards 93010 are JUNK...!!!! They are so wavy that I only get .010 offset. They don't sit in between the valve and retainer smooth and tight. Going to try the Summit ones
Crane offset keeper part # 99095-1 (Part # 43093010 Howards Cams 93010) Thanks! I missed this on my heads. I did break in my cam already. My cam has 0.477 int./0.480 exh. lift. (COMP Cams CL12-242-2) I will have to fix this.
I just pulled my pressed in studs on 906 vortec heads. I used anti seize grease to lubricate the nut on the stud being pulled . if the nut starts getting hot move to the next stud and let that one cool off. It looked like most of the studs are stake and were difficult to pull and a couple came out easy. do not use a cheap nut use a valve stud nut which is hardened.
Piss Cutter... Have you ever looked at the Alex's Spring Kit. Has special keepers that make the clearance to like .550 lift. Affordable. I do like the Beehives for their performance. I went with Alex's however and they have performed very well. Have 15K in it now. Springs are like 130lbs seat pressure.
Do yourselves a favor and get the screw in studs with guide plates... Self centering roller rockers are more expensive and doing guide plates gives you more options!
Total newbie so don't hate. I'm redoing a L48 Corvette my uncle gave me after I returned from Iraq. I finally have the time to get on it. I understand the L48 vettes only put out about 180hp so I picked up a set of rebuilt 062 Vortec heads and intake to reuse the quadrajet carb. I have a L79 cam for it as well. Do I need to change the pistons to accommodate the heads? Do you have any other suggestions? Again, new guy, don't hate..lol
I used .030 keepers on the beehive springs with a 501 505 lift cam will I be ok or do I need to do something different it also gave me .020 more fore my rocker self aligning at the rocker what do you think thanks
Did you check what your seal to retainer clearance was? Installed height should be around 1.780 with the .030 keeper and the 787 retainers. Installed at 1.780 a LS6 spring is good till .530 lift

I will be installing a mild hydraulic roller cam in my stock 906 vortec heads with .450/.450 lift. I would like to use my stock retainers/keepers because they seem to be in good condition and I’m on a budget. Any spring recommendations would help thanks and awesome informative video!
If I run a 500 lift cam I don’t have to cut anything on the heads just get the same setup u have comp cams springs retainers and keepers I’ll be able achive 530lift even tho I won’t go that high
Do you have a minimum clearance between the self aligning edges and the retainer/ keepers? Also, if I have to grind/ file my aligners, what’s a “safe” amount to leave on the rocker? I’m hitting now on my intakes, with my new full roller rockers, and my 787’s with .050 offsets, but they have huge alignment guides on them! I ordered some of the .030 offsets, that I’m going to try on just the intakes, since the exhausts are fine (.520 exhaust lift, and .525 intake Summit’s LT-4 hot cam copy Sum-8802 roller cam). What limits do you suggest on the valve tip (intake side), and clearances with the alignment edges? Thanks in advance! LOVE ALL YOUR VORTEC VIDS! I’ve been watching them over and over for years now!!
Hello brother I really love you're content its been really help full I've done the porting on my 062 heads to how you explained i ordered the 12499224 ls6 springs but I got for some crazy reason the 12713265 springs what is the difference if you can help I would really appreciate it thank you for all your content keep on uploading cuz I as well as my family and friends will be posted from my home to yours stay safe
Outstanding work 👊🏼 I’m looking to freshen up my 94 impala SS. I just ordered Try-Y gen 2 ceramic coated headers with 2 1/2 inch XL spintech mufflers. The car has 105,000 & I plan on keeping the stock cam. I’m looking into beehive comp springs with 1.6 RR. The plan is installing them under the hood down the road. I have been a mechanic for 19 years & have never done them on an Lt-1. Any advice would be greatly appreciated. This car is in honor of my brother that was killed in 94, he was a marine. I must say that you are doing a great thing by sharing your knowledge & I just subscribed 👊🏼🏴☠️🇺🇸 🔝
Yeah man not hard to do, Use a leak down tester to pressurize the cylinder at TDC, then use a on car head valve spring compressor to push the spring down. Then carefully use a magnet to remove the keepers. *the compressed air hold the valve up* Let me know if that doesn't answer your questions and I can do a video on it Cheers!
The 26915 comp springs are the ones I’m reading about. I have the other part numbers in my tool box for the retainers & whatnot. My question 🙋🏻♂️ is which tool would make it easier for removing the springs. I have the spinning star ⭐️ one in my box. I read about another that’s a lower profile, to make the process quicker for the firewall side. I’m in no rush at the moment cause I’m still waiting on parts. Again, I sincerely thank you for sharing your knowledge 💯🏴☠️🇺🇸
What's up man? Love your videos. I have a quick question for you, I am doing the ls6 spring on some 906 vortecs and have notice the bottom of the spring is pretty snug to the guide boss. Will that be ok? I've always been told you need .010 clearance.
@@cuttersperformance Hey there! I am getting ready to install some beehive springs - I want to install screw in studs. Can you recommend a stud kit? I will be staying with stock rockers, not going radical with the cam, just a 280H. If you could recommend some studs that would work without cutting the bosses and would work with the factory rocker I would appreciate it. Also, what is a good tap? THANK MAN!
I have had good luck with pioneer 850001 stud kit. Buy yourself a good quality tap from your local hardware store, the heads tap fairly easily I will be posting a stud video within the next week

Have you ever ran a solid roller cam on vortec heads. I am running lt1 heads n a buddy gave me a street roller 290* .555 lift. Going to need a stout spring. You’re the most knowledgeable on these style heads
Ive actually never ran a solid lifter cam with vortec heads. Typically the vortec headed engines im doing are for guys not wanting to make adjustments. I may consider a mechanical roller for the dingle ball because of the price of retro fits right now.
The LS6 springs are designed for a Hydraulic roller cam. They work with stock to mild Hydraulic roller cams and Ive used them with flat tappet cams aswell
Hi! Great video, but what about the valve spring outer diameter? The LS springs are larger then the vortec springs, the valve spring seat is about 1.240 on my vortec head and the Comp Cams springs in the video is 1.282 and the GM springs are 1.290. Thanks!
This was a good video my only thing is I’m running .450 with 100% stock heads and it runs great I’ve heard mostly that you can run about .465 with stock heads as long as it’s not a high duration cam but I love your content keep it up man
Do you have a pretty mild or stock cam? Stock springs are pretty weak for any sort of performance cam. I'd be very nervous running past .450 lift personally Thanks for the positive feedback! Vortec porting / flow bench videos coming soon!
@@cuttersperformance also I 100% agree I know I’m cutting it close at about .030 clearance but I haven’t had any issues but I won’t run anything over .450 without beefed up springs and retainers
@@anthonyspangler1537 Hit me up if you need a spring kit for those suckers! I got springs to cover from mild to wild, no machining and direct drop in! pcperformance1@outlook.com
could you file/grind a bit off the bottom most part off the keeper or retainer just enough to clear those rarely fail due to weakness so that says they are stronger than needed but obiously offset keepers would better
Very good infos thanks ! I have stock bottom end l31 vortec engine My heads have been ported, 3 angle porting, and beehive springs. So i want to put a Xe268h-10 cam .wich has .480 full lift.. In your opinion should i keep the stock self alinign rocker arms or i should buy the aftermarket rocker arms ? Surely i will also take a look at the clearance between the retainers and the rocker
Gen 1 350. Vortec heads. Just swapped out rocker studs in case future upgrades on cam. Bought L79 cam. Recommendations on rockers.. interested in rollers but know I need self aligning because the vortec don't have guide plated...
Yeah, you can typically use a roller tip rockers with factory valves and offset keepers. The exhaust valve is no problem as the tip is longer, but the intake valve you have to check for clearance
Thanks for the video. Question, I have a new pair of 062 heads I bought years ago and have been saving. They had the Z28 beehive springs installed by a shop, and I was told the were checked to .480 lift. Only planning to go .440 lift on the cam. Are the press in studs ok? Thanks.
This is exactly what I needed! Im running .600 valve springs for an ls6 on my heads, screw in studs and offset keepers, but what are the best or what self aligning rockers would you recommend?
I've had good luck with the comp cams roller tip rocker arms Especially with offset locks locks becuase you lose some of the valve tip. Make sure you check your rocker to retainer clearance *See my vortec rocker arm video
I was wondering if you had flow numbers for 14011034 Bow-tie phase 2 heads if they are a good head I sure would appreciate it. Love watching your video's. You make it a lot easier to work on heads. THANKS
FANTASTIC JOB, I'M DOING VORTECS ON MY 1981 CORVETTE WITH A COMP CAM WITH 480 MAX LIFT THIS COVERS IT ALL...THANK YOU , BEHIVE COMP OR LS6 WHICH DO YOU RECOMMEND
So, will the stock self-aligning rockers not work at all with the offset keepers? Just need to know, if not, I can send the keepers back I bought and just got with a 480 or less cam. Let me know when you can, I just cannot spend about 250 on rocker arms. THanks, brother - again awesome content!
Yeah but you will want to check your rocker to retainer clearance when using offset keepers Also this video may answer some questions ua-cam.com/video/4CbmJC8kIAw/v-deo.html
@@cuttersperformance Man you are amazing, and this content - fantastic. May I ask one more question? I am going with a comp cams 12-246-3 which is .490/.490 - With the beehive springs and just the retainers do you think that might be okay without the offset keepers? I mean I will measure but it is darn close just based on calculations. If I didn't have to use the offset keeps that would make me feel safer. Once again, I am spreading the word about your channel man, you are doing GREAT work!
You will have to check your specific heads for installed height ect. Also make sure your valve seals are fully seated on the guide. Ideally you want at least .050 clearance from the seal to the retainer. If it's going to be less than that, I'd suggest using the offset keepers You'll also want to verify your actual total lift once the heads are mocked up on the engine with the rocker arms that you will be using as there can be a variance Cheers!
@@cuttersperformance Thank you so much for the help! Your videos and your responses have made it possible for me to dig into these engines...I cannot thank you enough for being so awesome man!
Great video. I've used this one plus other vids you have to rebuild my L31 Vortec heads. From a newb - thanks. Some updates if helpful: 1) The part # for the GM springs has been replaced with GM (19420455). They have changed color also to a gun metal gray. Summit Racing has them. 2) Finding the valve locks/keepers has been challenging. When searching for 99095-1, I'm being redirected to 99097 or 98. Where to get the keepers?
@@cuttersperformance One more question: Since the stock self-aligning rockers are a no-go with the offset keepers, what is your recommended rocker? Thanks again for channel.
Hey I was told and many write ups online using ls6 springs and comp cam retainers 767-16 u could run a lt4 hot cam so what you are saying is even with the ls6 springs and retainer u can only still get a max lift of .480 with 1.5 rockers
You will have to check on your heads but you will find that running the 787 on vortec heads won't give you the proper spring installed height with stock keepers That will two things: 1) Your valve spring just went from a max lift of say .550 with a 1.800 installed height to a max lift of .500 installed at 1.750. 2) your seal to retainer clearance with proper safe clearance will only be around. 480 maybe .500 with stock seals. So Basically no matter how you do it with stock keepers and Ls6 springs past .500 lift you are pushing the limits. Will it work slightly past .500 with stock keepers...maybe but is it worth the risk? You will have to do the measurements on the heads, you can use the method shown in the video without having to but any special tools Let me know if you have any questions
@@cuttersperformance I emailed you on outlook if it was yours and wanted to install a lt4 hot cam without taking the heads of what would u do thanks for the info in advance the email that I sent came from smokie535@yahoo.com thanks
Send me a email Patobrien31@outlook.com I have special offset retainers and valve seals that allow .530 lift with stock keepers. Ls6 springs would work as long as you don't have alot of duration
I dial indicator would work if you have one. They also make special spring pocket dial indicators for checking spring height. But this way works great for most people with basic tools at home, and after the first spring its easy to quickly check the rest
Lots of confusion. Why does Summit advertise max lift for their Vortec heads as .520? These are Summit Racing Part Number: SUM-151124 Did they modify them for more lift?
Thank you for this information!! I will be doing the same thing to my heads but I've hit a road block when it cone to ordering my pushrods... my cam is 495/502 meiling 22280. Will the factory size pushrods work?
Just about everything can change the pushrod length, but if your going with vortecs on a roller block then the factory pushrods of 7.200 should be close. You will not know for sure until you assemble everything and check the pattern on the valve tip
How high of rpm can you rev if you put all the parts in? I have a former step-dad that has a 355 with the smaller valve vortec heads. He can only rev it to 5200 now
@@cuttersperformance im interested in a kit with comp cam springs and retainers as well as the offset keepers. Ready to purchase! This should give me .550 lift correct?
Pat, did you have to machine the heads to accept the LS6 springs? I like the Summit 8802 hydraulic roller cam but, it has .525 lift. So, the offset keepers would get us to .530 lift but do the spring pockets need to be machined for the beehives?
Check out this video aswell, no machiene work done to the heads. I ran the similar LT4 hotcam recently with this setup, worked great with the ls6 equivalent summit springs up 6200 rpm all day. ua-cam.com/video/UZosxGQyGMs/v-deo.html
Trying to spec out parts for my 98 5.7 vortec...so could I run offset keepers, the comp retainers and drop in ls6 springs rated at .600 lift and clear a cam with .550 lift on intake and .540 on exhaust?
I'm trying to set up my Vortec heads to support a stock camshaft pulled from a 1993 Camaro's LT1 engine. From what I've been able to find, that cam should have a .480 lift. Just to make sure I'm understanding correctly, all I should have to do to be able to support that .480 lift is swap to the LS6 springs, right? I have the heads at a machine shop now for a valve job, and they seem to think the factory springs should work. You mention that Vortec stock max lift is .420, but later mention stock safe max lift is .480; is this difference based solely on swapping to the LS6 springs?
I will post a newer video that explain things a bit more in depth. The stock springs aren't too good much past the factory lift of .420 to .430 with a mild roller. You can push them to around .460 with a mild flat tappet
I got a l31 crate motor and I am pretty disappointed with it I wasn't expecting much but still not alot of power I want a 480 480 cam should I use that offset keeper to be on the safe side
Ls springs 560lift. 600lift all over ebay. The offset keepers i understand. Is there something special about the retainers. Is there a standard and a 7 degree retainer. What type of retainer is used. I am upgrading from stock flat tappet to a stock style roller (lt1).
Hi, I have one of you spring kits. Would it b OK to run these beehive springs with a new cam break in xe268. Worried about to much spring pressure during break in. Thanks
Hey Geoff! I've broken in lots of flat tappet cams with those springs with no issues. Lots of break in lube on the cam and lifters, break in oil and proper break in procedure and you'll be golden!
I do have a kit, but currently back ordered as I can't get stock right now because the manufacturers are behind. But....if your a vortec fan be sure to Subscribe as there's a giveaway coming up very soon
Great video! Very informative! I’m looking for a nice cam and spring kit setup for my ‘98 Chevy Silverado with vortec 350. Do you recommend one with a nice lope(like with a mutha thumpr or thumpr cam sound)?
Hey bud , I wanted to let you know I enjoy and appreciate your video's. I have a question for you also. I recently ordered a set of the ls6 beehives from summit racing. There store brand and they were way to tight of a fit around the guide bosses. So i ordered another set of howards cams beehives that they recommended for my cam. They fit the bosses with room to spare and the outside lip of the spring pocket holds them in place pretty well. Do you think this setup is acceptable or should i rely solely on the guide boss to keep the spring in place. Probably have about .015 to .020 clearance between the spring and the guide boss.
What size are your guide bosses? A ls6 spring will typically fit perfect over a clean stock guide. i have has a few sets that ive has to take a sanding roll to clean up the guide a bit more for them to fit. As for you new springs if the outside pocket holds them then you should should be ok. A normal spring locator has about .010 clearance. Cheers!
@@cuttersperformance they range in size from .854 to .857 the springs i got from summit are around .855 id i ordered the other set of howards cams they are .900 id and seem to fit ok just a little wiggle room between them and the bosses but the lip around the outside of the spring pocket holds them in place pretty well. Thanks.
Hi, will these Beehive Springs work on my 1999 Dodge 5.9l 360 Magnum Gas Engine..??.. I plan on buying all parts needed for my Cylinder Heads setup real soon.. Itself will stay mostly OEM with Porting the Heads.. Tanks...
what stops someone from running +.050 locks on stock vortec retainers, say with a z28 spring without the damper? i have a "395" ramjet cam that id like to run with 1.6 rockers, which would make it .460/.481 lift. would it increase the retainer to guide clearance enough?
Just subscribed! Thank you, what valve guide seals are you using? I’d like to replace mine, maybe allow for more lift, I have a mild 350 going together, using a comp CL12-600-4 cam
Are you in a huge rush for the seals? I usually stock the viton seals for vortecs heads (stock guides) but im currently sold out. They will not give you much different clearance than the stock seals that are seated all the way down but they are better seals and easier to install than the steel shell oe ones
@@cuttersperformance I’m rebuilding a set and was just curious about them, I’m doing everything your recommended here in the video, thank you for the great video!

This video is very helpful I tried to purchase one of your kits but you said you do not have any available as of now. I just have one more question if you decide to cut down the valve seal guide with comp cams tool 4726 for even more lift how much would you have to take off ?
Hey Pat!! I’m looking to run this set up on my vortec heads but I can’t seem to find those Crane Keepers anywhere..? Even coming up short on the internet. Do you have any for sale or know where I can buy some?
Thanks man! You've just solved my problem of running a .506" lift cam without having to do any machining on my Vortec heads!
I cut my guide bosses down on my vortecs with the comp cams tool, installed Z28 springs without the dampers, and have been driving it 8+ years with zero problems.
I started cutting the guide boss down with a seal cutter and a drill more that 30 years ago
You can get .100 longer stainless valves cheap from erson, with longer hardened pushrods also to keep geometry correct . This avoids what may be expensive machine work to cut the guides down ! Hope this helps.

Someone mentioned to me that they had seen a UA-cam video about swapping to complete LS valve train. I don't remember, they said they were the 1.99" intakes and 1.55" exhaust. Upgrading to a bronze 1/2" odd guide for the .312" valve stem, as well as the LS6 springs. I haven't found anything on this. I've found plenty of videos, swapping springs. Yours is the most comprehensive on the spring swap. But I'm wondering if there is any advantage, performance-wise, flow-wise or weight-wise with that kind of swap. All I know is is from what I've been finding in researching, is that the stock 1.94s and 1.50s are pretty much better off left alone rather than going to a 2.02 and 1.60. Have you ever seen or heard about anything about the valve & spring swap (and guide) upgrade?
I dig the low tech but simple measuring technique of using the wire coat hanger
I've been looking everywhere for # 99095-1 keepers and they are OOS everywhere. I can find Howards 93010 keepers. They are a forged version with +.050 and seem to be a little cheaper.
Summit racing part# SUM-174003-4
@@cuttersperformance The Howards 93010 are JUNK...!!!! They are so wavy that I only get .010 offset. They don't sit in between the valve and retainer smooth and tight. Going to try the Summit ones
Crane offset keeper part # 99095-1 (Part # 43093010 Howards Cams 93010)
Thanks! I missed this on my heads. I did break in my cam already. My cam has 0.477 int./0.480 exh. lift. (COMP Cams CL12-242-2) I will have to fix this.
I just pulled my pressed in studs on 906 vortec heads. I used anti seize grease to lubricate the nut on the stud being pulled . if the nut starts getting hot move to the next stud and let that one cool off. It looked like most of the studs are stake and were difficult to pull and a couple came out easy. do not use a cheap nut use a valve stud nut which is hardened.
Thats the scary part, some dont come out nicely and and some do. Some come out very easily haha
Piss Cutter... Have you ever looked at the Alex's Spring Kit. Has special keepers that make the clearance to like .550 lift. Affordable. I do like the Beehives for their performance. I went with Alex's however and they have performed very well. Have 15K in it now. Springs are like 130lbs seat pressure.
When you can't run guided rockers you can run head gaskets for 90s LT1 they have rocker guides made in to the gasket
Do yourselves a favor and get the screw in studs with guide plates... Self centering roller rockers are more expensive and doing guide plates gives you more options!
Total newbie so don't hate. I'm redoing a L48 Corvette my uncle gave me after I returned from Iraq. I finally have the time to get on it. I understand the L48 vettes only put out about 180hp so I picked up a set of rebuilt 062 Vortec heads and intake to reuse the quadrajet carb. I have a L79 cam for it as well. Do I need to change the pistons to accommodate the heads? Do you have any other suggestions? Again, new guy, don't hate..lol
Great vijeho. You answered a lot of questions, thanks for posting.
I use Dow pins on my stock studs I had a 292 510 Cam and never had a problem
Thanks Mang. Gonna put vortec heads on my 406 sbc

I used .030 keepers on the beehive springs with a 501 505 lift cam will I be ok or do I need to do something different it also gave me .020 more fore my rocker self aligning at the rocker what do you think thanks
Did you check what your seal to retainer clearance was? Installed height should be around 1.780 with the .030 keeper and the 787 retainers. Installed at 1.780 a LS6 spring is good till .530 lift

I will be installing a mild hydraulic roller cam in my stock 906 vortec heads with .450/.450 lift. I would like to use my stock retainers/keepers because they seem to be in good condition and I’m on a budget. Any spring recommendations would help thanks and awesome informative video!

If I run a 500 lift cam I don’t have to cut anything on the heads just get the same setup u have comp cams springs retainers and keepers I’ll be able achive 530lift even tho I won’t go that high
Do you have a minimum clearance between the self aligning edges and the retainer/ keepers? Also, if I have to grind/ file my aligners, what’s a “safe” amount to leave on the rocker?
I’m hitting now on my intakes, with my new full roller rockers, and my 787’s with .050 offsets, but they have huge alignment guides on them! I ordered some of the .030 offsets, that I’m going to try on just the intakes, since the exhausts are fine (.520 exhaust lift, and .525 intake Summit’s LT-4 hot cam copy Sum-8802 roller cam).
What limits do you suggest on the valve tip (intake side), and clearances with the alignment edges? Thanks in advance! LOVE ALL YOUR VORTEC VIDS! I’ve been watching them over and over for years now!!
You'll want at least .055" nubs aligning the rocker to the valve tip and atleast .025 clearance from the rocker to the retainer or keepers
Great content bro keep it up from new Zealand 😊😊
Hello brother I really love you're content its been really help full I've done the porting on my 062 heads to how you explained i ordered the 12499224 ls6 springs but I got for some crazy reason the 12713265 springs what is the difference if you can help I would really appreciate it thank you for all your content keep on uploading cuz I as well as my family and friends will be posted from my home to yours stay safe

Outstanding work 👊🏼 I’m looking to freshen up my 94 impala SS. I just ordered Try-Y gen 2 ceramic coated headers with 2 1/2 inch XL spintech mufflers. The car has 105,000 & I plan on keeping the stock cam. I’m looking into beehive comp springs with 1.6 RR. The plan is installing them under the hood down the road. I have been a mechanic for 19 years & have never done them on an Lt-1. Any advice would be greatly appreciated. This car is in honor of my brother that was killed in 94, he was a marine. I must say that you are doing a great thing by sharing your knowledge & I just subscribed 👊🏼🏴☠️🇺🇸 🔝
Yeah man not hard to do,
Use a leak down tester to pressurize the cylinder at TDC, then use a on car head valve spring compressor to push the spring down. Then carefully use a magnet to remove the keepers.
*the compressed air hold the valve up*
Let me know if that doesn't answer your questions and I can do a video on it
Cheers!
The 26915 comp springs are the ones I’m reading about. I have the other part numbers in my tool box for the retainers & whatnot. My question 🙋🏻♂️ is which tool would make it easier for removing the springs. I have the spinning star ⭐️ one in my box. I read about another that’s a lower profile, to make the process quicker for the firewall side. I’m in no rush at the moment cause I’m still waiting on parts. Again, I sincerely thank you for sharing your knowledge 💯🏴☠️🇺🇸
Great vid I wanted to do this but was unsure now I know. Thank you.
What's up man? Love your videos. I have a quick question for you, I am doing the ls6 spring on some 906 vortecs and have notice the bottom of the spring is pretty snug to the guide boss. Will that be ok? I've always been told you need .010 clearance.
Sometimes, the guides will need a casting clean-up with a sanding roll on a die grinder. Spring should slide on with minimal effort
@@cuttersperformance awesome man! Thanks for the fast response and keep up the awesome work!
Amazing description of what’s going on! Thank you

Have you ever ran a solid roller cam on vortec heads. I am running lt1 heads n a buddy gave me a street roller 290* .555 lift. Going to need a stout spring. You’re the most knowledgeable on these style heads
Ive actually never ran a solid lifter cam with vortec heads. Typically the vortec headed engines im doing are for guys not wanting to make adjustments.
I may consider a mechanical roller for the dingle ball because of the price of retro fits right now.
Like the video but was wondering if it would be safe to use a hydraulic roller cam with Vortec heads using ls6 valve springs
The LS6 springs are designed for a Hydraulic roller cam. They work with stock to mild Hydraulic roller cams and Ive used them with flat tappet cams aswell
great videos. These vortec 350 long blocks are cheap now. Great builders or throw a carb, hei and go.
Real fine video! Thanks! No nonsense and extra puffing....
So I can safely run stock keepers and retainers with a ls6 as long as I don’t go over .480 lift right?
Yes, but you should do the checks shown in the video to be sure. Make sure your valve seals are seated all the way down aswell
Pat, what's a good self aligning roller rockers for a behived only vortec head ? I did pull the studs and put in threaded. No guid plates. Tango
Hi! Great video, but what about the valve spring outer diameter? The LS springs are larger then the vortec springs, the valve spring seat is about 1.240 on my vortec head and the Comp Cams springs in the video is 1.282 and the GM springs are 1.290.
Thanks!
This was a good video my only thing is I’m running .450 with 100% stock heads and it runs great I’ve heard mostly that you can run about .465 with stock heads as long as it’s not a high duration cam but I love your content keep it up man
Do you have a pretty mild or stock cam? Stock springs are pretty weak for any sort of performance cam.
I'd be very nervous running past .450 lift personally
Thanks for the positive feedback!
Vortec porting / flow bench videos coming soon!
@@cuttersperformance it’s a sum-8800 stage 1 cam it’s pretty mild with a almost stock smooth idle
@@cuttersperformance also I 100% agree I know I’m cutting it close at about .030 clearance but I haven’t had any issues but I won’t run anything over .450 without beefed up springs and retainers

I’m only running .450 lift is there a slightly beefier spring available I’m looking for something slightly heavier but nothing crazf
VERY informative , Thank You .
could you file/grind a bit off the bottom most part off the keeper or retainer just enough to clear
those rarely fail due to weakness
so that says they are stronger than needed
but obiously offset keepers would better
Yes you can but you the offset keeper installs the spring at the proper height aswell
Very good infos thanks !
I have stock bottom end l31 vortec engine
My heads have been ported, 3 angle porting, and beehive springs.
So i want to put a Xe268h-10 cam .wich has .480 full lift..
In your opinion should i keep the stock self alinign rocker arms or i should buy the aftermarket rocker arms ? Surely i will also take a look at the clearance between the retainers and the rocker
Gen 1 350. Vortec heads. Just swapped out rocker studs in case future upgrades on cam. Bought L79 cam. Recommendations on rockers.. interested in rollers but know I need self aligning because the vortec don't have guide plated...
Comp cams or PRW self aligning roller tip rockers work well, especially if your trying to use stock valve covers
As far as the rocker concern with the offset keeper, could this be remedied by using self aligning roller tip rockers?
Yeah, you can typically use a roller tip rockers with factory valves and offset keepers. The exhaust valve is no problem as the tip is longer, but the intake valve you have to check for clearance
Hey what valve seals did you use a part number would be great please
Thanks for the video. Question, I have a new pair of 062 heads I bought years ago and have been saving. They had the Z28 beehive springs installed by a shop, and I was told the were checked to .480 lift. Only planning to go .440 lift on the cam. Are the press in studs ok? Thanks.
This is exactly what I needed! Im running .600 valve springs for an ls6 on my heads, screw in studs and offset keepers, but what are the best or what self aligning rockers would you recommend?
I've had good luck with the comp cams roller tip rocker arms
Especially with offset locks locks becuase you lose some of the valve tip. Make sure you check your rocker to retainer clearance
*See my vortec rocker arm video
I was wondering if you had flow numbers for 14011034 Bow-tie phase 2 heads if they are a good head I sure would appreciate it. Love watching your video's. You make it a lot easier to work on heads. THANKS
Can you use factory retainers with the beehive springs and offset keepers
No the 787-16 retainers must be used with the beehives
I didn’t check because you checked for me!👍🏾 Thanks 🙏🏾
FANTASTIC JOB, I'M DOING VORTECS ON MY 1981 CORVETTE WITH A COMP CAM WITH 480 MAX LIFT THIS COVERS IT ALL...THANK YOU , BEHIVE COMP OR LS6 WHICH DO YOU RECOMMEND

@@cuttersperformance great thanks, Yes I have flat tappet
So, will the stock self-aligning rockers not work at all with the offset keepers? Just need to know, if not, I can send the keepers back I bought and just got with a 480 or less cam. Let me know when you can, I just cannot spend about 250 on rocker arms. THanks, brother - again awesome content!
Yeah but you will want to check your rocker to retainer clearance when using offset keepers
Also this video may answer some questions
ua-cam.com/video/4CbmJC8kIAw/v-deo.html
@@cuttersperformance Man you are amazing, and this content - fantastic. May I ask one more question? I am going with a comp cams 12-246-3 which is .490/.490 - With the beehive springs and just the retainers do you think that might be okay without the offset keepers? I mean I will measure but it is darn close just based on calculations. If I didn't have to use the offset keeps that would make me feel safer. Once again, I am spreading the word about your channel man, you are doing GREAT work!
You will have to check your specific heads for installed height ect. Also make sure your valve seals are fully seated on the guide.
Ideally you want at least .050 clearance from the seal to the retainer.
If it's going to be less than that, I'd suggest using the offset keepers
You'll also want to verify your actual total lift once the heads are mocked up on the engine with the rocker arms that you will be using as there can be a variance
Cheers!
@@cuttersperformance Thank you so much for the help! Your videos and your responses have made it possible for me to dig into these engines...I cannot thank you enough for being so awesome man!
@Donald Warwick No problem man! I appreciate the support
Cheers!
Great video. I've used this one plus other vids you have to rebuild my L31 Vortec heads. From a newb - thanks.
Some updates if helpful:
1) The part # for the GM springs has been replaced with GM (19420455). They have changed color also to a gun metal gray. Summit Racing has them.
2) Finding the valve locks/keepers has been challenging. When searching for 99095-1, I'm being redirected to 99097 or 98. Where to get the keepers?
Glad to hear! I will be getting more stock on keepers and valve seals soon if your interested
Cheers!
@@cuttersperformance One more question: Since the stock self-aligning rockers are a no-go with the offset keepers, what is your recommended rocker? Thanks again for channel.
@@mikevosper5604 did you end up finding the recommended rocker ?
@@adancortes3568 looking for rockers for this set up as well
So what retainers can I use for vortec heads with .500 lift cam,stock seals and melling vs-739R springs
Hey I was told and many write ups online using ls6 springs and comp cam retainers 767-16 u could run a lt4 hot cam so what you are saying is even with the ls6 springs and retainer u can only still get a max lift of .480 with 1.5 rockers
You will have to check on your heads but you will find that running the 787 on vortec heads won't give you the proper spring installed height with stock keepers
That will two things:
1) Your valve spring just went from a max lift of say .550 with a 1.800 installed height to a max lift of .500 installed at 1.750.
2) your seal to retainer clearance with proper safe clearance will only be around. 480 maybe .500 with stock seals.
So Basically no matter how you do it with stock keepers and Ls6 springs past .500 lift you are pushing the limits.
Will it work slightly past .500 with stock keepers...maybe but is it worth the risk?
You will have to do the measurements on the heads, you can use the method shown in the video without having to but any special tools
Let me know if you have any questions
@@cuttersperformance I emailed you on outlook if it was yours and wanted to install a lt4 hot cam without taking the heads of what would u do thanks for the info in advance the email that I sent came from smokie535@yahoo.com thanks
Sorry man didn't see the email maybe check the address again

@@cuttersperformance hey yea I put the wrong email in I got it right this time thanks
What an awesome video! Im using a .480 lift, could I get away with just using ls6 springs?
Send me a email
Patobrien31@outlook.com
I have special offset retainers and valve seals that allow .530 lift with stock keepers. Ls6 springs would work as long as you don't have alot of duration
What rocket arms would u suggest using with the off set retainers, screw in studs, and the ls6 springs?
Comp cams 1417-16 work well
Wouldn't a dial indicator work better?
I dial indicator would work if you have one.
They also make special spring pocket dial indicators for checking spring height.
But this way works great for most people with basic tools at home, and after the first spring its easy to quickly check the rest
3/8 diameter push rods eliminate the need for self aligning rockers
Lots of confusion. Why does Summit advertise max lift for their Vortec heads as .520?
These are Summit Racing Part Number: SUM-151124
Did they modify them for more lift?
They are an aftermarket casting, not a reconditioned factory casting. I believe they are made by Dart.
So is this process a more cost efficient way? Or would having the bosses machined a better way to go?
This was is usually cheaper as you typically have to buy these parts anyway when upgrading cams
@@cuttersperformance thanks man. I’m gonna go to my shop next week with this info. Have my heads done this way and add 1.60 exhaust valves
Thank you for this information!! I will be doing the same thing to my heads but I've hit a road block when it cone to ordering my pushrods... my cam is 495/502 meiling 22280. Will the factory size pushrods work?
Just about everything can change the pushrod length, but if your going with vortecs on a roller block then the factory pushrods of 7.200 should be close. You will not know for sure until you assemble everything and check the pattern on the valve tip
@@cuttersperformance thank you!
Which springs would be better for a .512” lift cam?
How high of rpm can you rev if you put all the parts in? I have a former step-dad that has a 355 with the smaller valve vortec heads. He can only rev it to 5200 now
These springs work with flat tappet cams and mild roller cams, ive used them at 6500 rpm no problem with a 1.94 valve
@@cuttersperformance would the offset keepers work good to?
@@logicalspark3496 yeah you need them to get the 1.800 installed height
@@cuttersperformance does it still make power at that high of an rpm.
@@logicalspark3496 yeah depending on cam
If i use the same vortech head upgrade with ls spings and cam you use on your 355 on a 305ho do you think it would work for a power increase
I checked your stuff on the same head and your right. Do you know where you got those offset keepers? Thanks
I will be getting more stock soon if your interested in some keepers and valve seals for vortecs
Why wouldn't pinning the rocker studs be sufficient?
They can be if done correctly. Only really needed if open pressure exceeds 300 to 325 lbs

@@cuttersperformance im interested in a kit with comp cam springs and retainers as well as the offset keepers. Ready to purchase! This should give me .550 lift correct?
@@cuttersperformance I also emailed you I am interested in a kit.
Pat, did you have to machine the heads to accept the LS6 springs?
I like the Summit 8802 hydraulic roller cam but, it has .525 lift. So, the offset keepers would get us to .530 lift but do the spring pockets need to be machined for the beehives?
Check out this video aswell, no machiene work done to the heads. I ran the similar LT4 hotcam recently with this setup, worked great with the ls6 equivalent summit springs up 6200 rpm all day.

Yes you can, ive done it. Just follow proper break-in if the can is new
Can u use these springs in 305 vortec heads???
Yes you can
Can you use the stock rocker arms with this setup
I'm trying to set up my Vortec heads to support a stock camshaft pulled from a 1993 Camaro's LT1 engine. From what I've been able to find, that cam should have a .480 lift. Just to make sure I'm understanding correctly, all I should have to do to be able to support that .480 lift is swap to the LS6 springs, right? I have the heads at a machine shop now for a valve job, and they seem to think the factory springs should work. You mention that Vortec stock max lift is .420, but later mention stock safe max lift is .480; is this difference based solely on swapping to the LS6 springs?
I will post a newer video that explain things a bit more in depth. The stock springs aren't too good much past the factory lift of .420 to .430 with a mild roller. You can push them to around .460 with a mild flat tappet

Crate motor, it probably has the later Mexico made vortec heads, not nearly as good as the made in the US ones.
Ls springs 560lift. 600lift all over ebay. The offset keepers i understand. Is there something special about the retainers. Is there a standard and a 7 degree retainer. What type of retainer is used. I am upgrading from stock flat tappet to a stock style roller (lt1).

Hey bud , I wanted to let you know I enjoy and appreciate your video's. I have a question for you also. I recently ordered a set of the ls6 beehives from summit racing. There store brand and they were way to tight of a fit around the guide bosses. So i ordered another set of howards cams beehives that they recommended for my cam. They fit the bosses with room to spare and the outside lip of the spring pocket holds them in place pretty well. Do you think this setup is acceptable or should i rely solely on the guide boss to keep the spring in place. Probably have about .015 to .020 clearance between the spring and the guide boss.
What size are your guide bosses? A ls6 spring will typically fit perfect over a clean stock guide. i have has a few sets that ive has to take a sanding roll to clean up the guide a bit more for them to fit.
As for you new springs if the outside pocket holds them then you should should be ok. A normal spring locator has about .010 clearance.
Cheers!
@@cuttersperformance they range in size from .854 to .857 the springs i got from summit are around .855 id i ordered the other set of howards cams they are .900 id and seem to fit ok just a little wiggle room between them and the bosses but the lip around the outside of the spring pocket holds them in place pretty well.

Are you in a huge rush for the seals? I usually stock the viton seals for vortecs heads (stock guides) but im currently sold out. They will not give you much different clearance than the stock seals that are seated all the way down but they are better seals and easier to install than the steel shell oe ones
