Time saver. He says $2,278.99 total.
I drive an Audi. This is freaking nothing.
Speed Inc does good work. They're not even in my state and I know about them 😁
Pretty cheap.
This is the EXACT information I was searching for. So many of these LS7s end up with full heads/cam/intake packages when they go in for this fix (and I obviously see why), but I was looking for the cost if I wanted to simply remedy the issue with good components and not go for an all out 600 RWHP build. Additionally, Speed Inc is the most local to my state, so this video knocked it out of the park for me. Thank you so much!
I’ll second that most ppl love to over inform you, we all know the car is built for extreme power but everyone isn’t interested in a insane setups.
$4k
Speed Inc for the WIN
Thanks for putting this together. I'm shopping for a C6 Z06 and was planning to include the cost for this repair when shopping. Great info here!
I’m looking into a c6 zo6 atm , great video man, and you are correct, not much info about this online. Thank you 🙏
Great video, very informative. I can’t thank you enough for the name of the shop because I’ve been having a hard time finding a good shop locally for me and they’re only about two hours away so that’s awesome. I have a 23,000 mile 07 Z06 and I’ve been afraid to push it. I would like this peace of mind as well so I plan on doing this in the spring.
At 19k miles my 2007 Z06 heads 🤦🏾♂️ had to be fixed so I called Texas Speed and got their kit 💰💰💰💯 im very happy now 😎 at 34k miles 👍🏾
How much was it?
Had Speed, Inc work on my 08' Z06 a couple weeks ago. GREAT JOB DONE. Props to TONY, the service manager. Great guy! Great Shop. Have used them before. Highly recommend. On budget and on time. Got my Z up to 600 rwhp. Needed a tune. Run 93.
Thank you very much for input on this highly debated issue.
Thanks for the tips man , def something ive been considering once I find the right c6 z06
Good luck with your search friend! The car market right now is absurd but I’m sure you’ll find a good one given some patience!
I've been seriously looking at buying one of these bad boys for months. Looked at several vids and appreciate your candor. Found one on-line I'm finally interested in with only 18k miles but has 4 previous owners. It's nerve racking trying to find the right one. It's a crap shoot buying with these known issues.
@@jamesw.6931 Hello James, thank you for responding. I wish I was in the position to pull the trigger, but the prices are still at a premium and I can't justify it. Have no idea when they'll come back to reality. But for you, it's an excellent time to sell and I would take advantage of it, especially if you don't plan on replacing your Vette. Bet you that you can get 20K more for yours today than you could have got 2 years ago. I wish you the best!!
I believe that the problem is real...i am just finishing my heads,cam,cai and exhaust on my 4500 mile 2012 Z06...i did the work and the package of parts cost 6200.00 so i feel for me that i intend to keep this car and tune it myself.
I couldn't help myself, I would have swapped heads, and installed a slightly more performance cam and headers. Its the labor that is the huge ticket item. Great video.
Great info!!! Think I'll get my heads done too!
🤣🤣🤪 silly goose. I’m sure the Kona heads are fine.
I’ve budgeted $5k for this issue during my current search for a C6Z. Nice to see that I may have some extra funds for go-fast stuff lol!
My 74k miles 07 Z06 just got all the full bolt on upgrade with bigger injectors, trunnion upgrade, new heads and cam...no issues with the valves or heads when they took off the old ones. Clutch is being upgraded to Stage 2 kevlar rated at 600 ftlb torque and getting new torque tube assembly....around 25k now total with all the parts and labor.
Till one drops SMH
Thank you for this. Missed out on that giveaway but I needed this information thank you
You’re welcome! But we have two more giveaways to do, both higher in value than the first. One of which is actually live right now! Ends October 31st, 2021.
Definitely worth it for the peace of mind!
Great info. Supposedly my brand new Chevrolet Performance LS427/570 (hot cam LS7) has the same issue. The good news is I have a 2 year 50k mile warranty to cover the issue.
🤘🤘
I'd check w/GM. They adressed the issue in later builds.
Who did you get your warrenty from?
@@ryanread5727 GM performance. Unfortunately they no longer sell this crate engine.
@@DetachedGarage I got one in July 2022. Car makes great power. 562 to the wheels. How did you diagnose that your engine had the issue? Wiggle test? How many miles did you dicover it?
I just bought a 2009 Z06 with 107k Miles. It’s pretty high and it’s what I could afford. So …
I’ll do the same thing you did for the peace of mind. But just remember, if mine passed 100k. You guys are completely fine !!
you got lucky, many people have had the valves drop, even after the fix
@@benfarr6049 do you know what the actual fix is? Each shop has their own idea and nothing is bulletproof with OEM casting heads.
I've had my 2007 Z06 for over 11 years and have studied the situation on line for nearly that long my favorite comment I ever read was "mine has 145,000 Mi on it I guess better check my clearances"
Great video very to the facts and where I have a LS7 it’s where I’m heading next spring
My 09 Z06 has 45k on it. I just bought it and it’s untouched. I wish I could get all that done for that price! 2,200 isn’t bad at all.
great video.....detailed and informative
Thank you for your video. I am currently looking at getting a C6 Z06 sometime next year, at first I was excited then heard everyone saying that they have very expensive problems. So I started thinking twice about it but after seeing your video then that's not bad at all.
How are they holding up and what kind of warranty did you get with it?
Hey I have a c6 z06 for sale if your in az
Dude the 20% restock fee is a load of crap, as they keep those parts in stock if it’s a busy LSshop, so 20% to do nothing..now it cost about 2hrs labor to just pull valve covers to look, lol.l
Beautiful Car! MGW is a must and for me I installed curb alert and backup camera...Oh, and Catch Can...
Corvette content especially C6 will bring you views!
Thanks for the video man, I just bought a 07 z with 32,000 miles so this is a video I’ve been looking for. We are from the same area lol so maybe we’ll run into each other some day
I used speed inc. when my lifters went bad on my C5z. They're an incredible group. I may pick up a c6z next week. I'll be going back to see them. If so, a cam may be in the works as well.
If you have ever so much as entertained the thought "should I go ahead and do a cam?" - the answer is 100%, yes, do it. It's worth doing while it's already apart... Even if it is only a slightly different from stock spec'd cam, it's the time to do it. (Remember: you don't have to go for a huge, choppy cam)
Doing an aftermarket camshaft affords a good chance to upgrade to a more robust timing chain/sprocket set, as well, for extra "insurance"...or even to just replace yours with a 0 miles oem timing set, which is not much of an added expense, especially for how important of a component it is! So yeah, unless you're CERTAIN that you'll only want a factory ls7 cam - like...forever - then definitely take this opportunity to go ahead and do an aftermarket camshaft while you do the valve guide stuff. 👍🏻
Hello there. I realize this video is over a year old. I just recently stumbled upon it and I am a new sub. With that said, I too purchased an 09 Z06. Has 12K miles on it completely stock. I am shopping around in my area for the head fix. I am getting prices of doing it all (head fix, cam and exhaust headers. I was wondering how have things been since you did this to your car and did you ever end up getting a cam and/or exhaust? thanks!
Love the vids
Just bought an 07z with 42k, dont know anything done under the hood but now i need to find a shop in west MA to do it
I used to believe it was a shop tactic to make money until my friend’s 07 Z06 with 20,000 miles dropped a valve and blew its LS7 while wide open at 140mph. GM techs verified the speed, but still warrantied the motor. It was just over $22,000 in parts and labor.
Wanna get my heads done for sure, but at 62k with no issues. Fingers always crossed lmfao.
How does the car change once you install headers? I mean a cam is something that does really change the way your car drives, but never heard of headers making a diffrence exept for sound and power.
Never heard of headers making a difference except for power... Interesting statement. Anyway, yes, headers - in conjunction with an intake and a tune - can give significant gains in the neighborhood of 70 rwhp. If you ONLY bolt on some headers, it won't make much difference as it takes a tune to make the difference and it needs to be able to breathe with an intake
How does the motor run now??
Just got an 18' Genesis G90 5.0 Ultimate (RWD) ... with a lot of persuasion from many Genesis reviews and testimonials, including yours, and I've only got one depressing question for you... does your Genesis feel slow and boring now that you are used to the Corvette? I was on the fence about buying something sportier than the G90 but I guess it's too late now. Haha... don't get me wrong. The Genesis is plenty fast. I'm just already growing accustomed to it. If you had it all to do over again, would you have gotten the Vette first? (Keep up the awesome content!)
Two completely different cars, but no the Genesis doesn’t feel boring now, slower yes for sure no debating. The Genesis is still my favorite 😬😬
The spark plugs were cheap because they were copper plugs. They wear faster so Id consider changing them after 20k miles. Iridium plugs last longer.
Duly noted thanks for the tip!
Does every c6 zo6 have these valve issues
Better to address the LS7 issue sooner than later, GM should refund anyone who fixed or replace it.
Thank you for sharing. Ironically I have an 09 Atomic orange Z06 with about 24000 km on it. I don't drive it anymore, as I'm trying to find a shop in Western Canada I can trust to do a competent job, like yours. I'm also looking to keep mine stock. I know our dollar is worth less than yours, but that seems super affordable and huge relief for potential engine failure and overhanging dread. Thank you for the breakdown of parts needed. I truly appreciate it ehhh 🇨🇦 Have fun in your Z :-)
Hey man I’m from Canada too how much did it cost you to fix the head?
@@60thirty22 Hello my fellow Canuck. Haven't found a shop yet I trust to do it yet. Might pull myself with a bud, and ship to Cali. ?
I have an 06 with 34000kms and I would like to find a good shop too. You find one? I'm in Vancouver and would like to know if you found a reputable place.
@@thorandmoljnir Imagine that!!!!. I just did :-) An old friend has a C6 Z06 that he races now, and has had plenty of engine work. But even better, one of their lead techs has same also, races it, while driving across US. He's met the developer of the LS7 at SEMA. Call Davenport Motorsports in Calgary and ask for Namala. He estimates they've done about 50 cars with now returns. Namala answered all my valve/guide ect questions in full confidence. Mine Z06 is booked for end of April :-) P.S. my buds cars has plenty of hard track days with about 700 rear horse, and no issues. I'm looking for stock reliability, and feel confident this is THE fix. Best of luck Thor
@@billmcmeekin7909
Sometimes I actually love the internet!
I appreciate the information. I'll definitely have to check them out. Thanks so much for letting me know!
Thanks for this video and content. I have a 2013 with 5300 miles. Bought it used and don’t know if mine was previously done or not. Does anyone know if they had straightened it out by the 2013 model year? If doing it, would most of you mod it while in there anyway? I would prefer to leave it stock, myself. Thanks in advance.
Should I just get a lsx 427?
You got a awesome deal 👌 😎
Basically needs a quality three angle vavle job with valve giudes re done. Or you might replace the heads.
Labor ain't cheap..but with what the shop did and replaced, a good price and insurance policy on many miles of happy driving!
Small price to pay to just enjoy and not worry!
i'm dropping my Z off to them in three weeks for the same procedure. hopefully have a good experience as well
How did it go, I’m afraid to drive mine until I get it fixed. Thing is I don’t know much about the engine parts so should I just take it to a shop and tell them I want the heads fixed ?
@@TexasFoldEm- I should be getting the car back in a week or two. I just dropped it off two days ago. Yes, for the bronze guides I would for sure find a reputable shop to do it properly. I was in the same boat, I didn't want to drive the car until this gets taken care of.
@@YuLost2X thanks for your reply. Are you getting aftermarket cylinder heads or are they just gonna send the GM heads to a machine shop and work them there. Also what were you quoted at for everything if I may ask ?
@@TexasFoldEm- just redoing the GM ones and yes, they send it to a machine shop and then re assemble etc. I initially got quoted 2500 but then because I already had a dual spring kit on they said if they can re use it will be right around 2100. Their prices are pretty fair I would.
That's the cost of getting into big horsepower I guess. Thanks for prepping me so I don't have a heart attack at a shop
I was looking at doing this to an ‘07. Emailed and called GM and Vette specialty shops that I trust and was wanting to fix the issue because of all the info on the internet. I was ready and willing to spend for the peace of mind. They wouldn’t take my money and said it’s a non-issue with my year/VIN. If I wanted to upgrade the parts, that’s another story. I still have
mixed feelings about the whole situation.
I have an ‘07 C6Z with 29k. They really said it’s a non-issue? 😂
Hi, we plan on taking our 2013 LS7 Corvette to Speedinc for valve guide correction. After taking your car to Speedinc, were you happy with the service and results of the work? We saw your video regarding the LS7 valve issue and we would like your feedback. Thank you.
Have you encountered any issues since the repair work?
Anyone who doesn't understand that GM does this on purpose, doesn't know GM.
Right. They hv a Dyno. n ALL the time n money . They knew it. N offset. Spending zillions to upgrade. For profit margin. AMAZING ….
I am strongly considering getting a c6 zo6 but I am too afraid of the exhaust valves dropping, if anyone has some advice feel free to let me know, thanks!
It can happen at anytime really.. low middle or high mileage I went heads/cam for the power but mainly so I can drive the car without being scared of it blowing up but I made it to 70k miles without it breaking. If you’re scared of them dropping you gotta get it done as soon as you get the car then. If you don’t wanna pay for that (cuz it IS expensive asf) then just don’t get one I still think my 2013 5oh was the best car I’ve ever owned, there’s a bunch of other great options
@@jgood5048 How must wear was found and how did look when removed?
@@jgood5048you said yours made it to 70k without breaking. What broke at 70k?
I've had my 2007 Z06 for over 11 years now I bought it as second owner...my total for the head repair to fix the dreaded valve issue and all other repair total have been $0.00
33k on my Z, I’ve never had it above 6000 for this reason. Bought with 32k and no knowledge of anything being done. Living in a small town, I don’t have anyone to take it to. I’ve done heads and cam in my garage on an LS before but I’d rather not do it again. I’m about 5.5 hours away from Schaumburg, I may consider getting the car to them somehow.
Seems like a solid shop, like I said a lot of local guys recommend them. Also from the research I’ve done online, $2200 seems more than fair comparatively. I wish I can tell you the quality of labor, but we shall see in due time. Let me know if you decide to take it there!
Salamat
I know no engine is bulletproof, however, does doing the “bare minimum” fix the head/ valve issue for good? Looking at Z06’s but am leaning towards a grand sport since of the head issues.
Unfortunately no… Best solution would be to swap head.
They're really just bringing the heads back into spec, putting better exhaust valves in, usually a longer guide to better seat the valve and reduce play, and use material that create less friction.
2200 is a lot less than 20k. i wouldve had a monster H/C setup installed but im not normal lol.
Will the RPM act inhibit people to be able to get this fix in the future?
Gooood question 🤷♂️ hopefully someone can chime in? I’m interested as well
Getting a 2007 Z06 today 30,000 miles i need this done too. Anyone know a reputable shop near me Allentown PA?
$2250 is very low here similar work would cost $4000+
Just buy some aftermarket heads and keep the old ones in case you ever sell the car
Rspec 5.0 ???
Damn $750 for labor?? I can't find a shop here that'll do it for a penny under $2400 and that's on the low end. Where do you live cuz I'm about to drive there and get mine done!
Better get them copper core plugs out of that car and get some iridium plugs.
My oil is getting consumed and burnt which leaves my back bumper black with exhaust residue after 4 ripps around the neighborhood ...does that make my car one of these bad head cars?
@@jamesw.6931 I did the wiggle test on the valves and they are moving.. could you please text me everything I need to supply the machine shop with to fix the heads..I would appreciate it and the cost of these parts you list for me that I need...thnx again
@@jamesw.6931 I Heard that if you submit your Bill for the repair to GM that they would pay you back..or was that b.s.?.. bastards would have recalled these vetts in a minute if it was a safety issue.thanx for your help brother
sweet
🤘🤘
Definitely a good price and for the peace of mind, worth it!
Agreed!
You were blessed. I’m scheduled to have basically the same thing done in the Baton Rouge area and my cost is $6,034 dollars.
Car was sent to Lingenfelter 8 months after it was purchased new and they installed super charger, cam, headers and full exhaust. I can not phantom why they didn’t address the valve issue while this work was being done.
My cost is a little higher because the supper charger has to be R&Rd. I hate to spend that much but If the engine were to get ruined I couldn’t afford to spend 20k plus right now to repair the engine.
Great video.
You got a cheap deal on the msd wires. I just bought a set and it was 130 bucks.
Great price!! Peterbilt ask me 2800 to install chicken lights on my 2022 Peterbilt. Lol
not bad at all
a year later and there is still not enough LS7 content and information
Omg just get new heads
The labor $750 for all of that?
Ouch
that is insanely cheap. I'm in Seattle and wouldn't be able to get any where near that price for labor. ended up pulling the heads myself and sending them down to AHP. would have pounced on$750 labor if the option existed where I live.
Tom wong at wongs performance in vancouver wa is your best bet. He has done many
boy this guy can talk whewwww.
Damn your z06 only has 15k miles!
Yessirrr
Heads Cam E85 Aux FP NW103
LT X Monster Clutch & tires
Just do it.
Everything there is a reasonable cost. All you save is the shop labor of $750
Idk why they used copper plugs? They dont last al long as platinum. 25k miles for std copper.
Really Gm should pay to have these heads fixed, but i guess like ford with 5.4L 3 valve engine they won't cover their own upgraded parts.
FYI 2011 to 2013 C6 Z06 dont have the head issues..
False. You have done 0 research. Z28s have head issues too.
I'm a chicken also I have a removed LS-7 and I'm terribly worried about hurting it. I want to place it into my 57 Chevrolet truck. Today.
I think it was a good idea not doing all mods at once. I've learned from my tuner on my car to do mods one at a time because if something goes wrong, you only have to troubleshoot one thing and you know exactly what it is.
Your tuner is telling you that to keep milking your pockets. All mods at once. Is a one time fee. He keeps you come back as a steady income. A serious speed shop will fix it right the first time.
Yea thats a pretty deceiving shop. I would not go to him lol
So keep paying him a retune
Get a grandsport ls3 and mod it, way to many z06s blow up, if your rich and dont care go for it if , you want a realiable corvett dont get a ls7
What shop did you use? Can you provide contact info?
Personally I think it's totally ridiculous if you want to donate your money give it to some charity the only way I would do that my C6 Z06 is if I put ported heads and a slightly modified cam then fine not to just fix the problem that never existed in the first place because of a few people that had recalls
If denial works for you, run with it!
Cheap insurance
Wow this is cheap. I am paying almost $4k for mine.
didnt have to do that with the genny
That’s cheap shop here quote me $5k🥺
It shouldn’t ever cost more than $2k-$3k
Truly expensive hobby, but it doesn’t make any sense to go through all of that labor and not upgrade to a better set of heads and cam,headers,and exhaust at least do the upgraded heads and camshaft. You could do the headers and exhaust yourself, but it is a very expensive hobby. and you missed a great opportunity at the end of the video to show the car laying down a patch.
