I can't wait to see those run! Numbers are almost the same as the 345's you did for me. I learned the hard way purchasing pro comp heads . Glad to see Summit not supporting the overseas crap. Eric thank you again for all you do and you willingness to help.
On BBC heads would love to have measurements on exhaust runners . Just because they need a ton of work compared to other heads . These as specially cause they look better than others. Thanks again for all the knowledge sir
Man, I'm just a street machine dude with already more HP than I can use; but if I ever come up and build another, I'll certainly keep you in mind. I bet those twisted wedges with some bee-hives would be like night & day compared to my old Dart II Iron Eagles. LOL
I bought the same heads for my pump gas 580 cid build. I was planning on putting the same dr 426 rml springs. plan on running 800 net lift. I am glad to see some testing on these.
@WeingartnerRacing no thank you. I have the heads 7 or 8 years due to my project being stalled. Definitely would buy from you in the future when I buy any heads and intakes. I would definitely rather support someone's small business Tham the big guys.
At 15:30, not quite, you don't lose the whole 50g it's closer to 20g, this is because the spring is neither sprung or un-sprung weight, it's a merger of both. So you have to at least half the difference as some of the difference is in the head side and some the retainer side, there is a calculation to work it out, but because the spring is being energized it's not 50-50.
I’m very interested to see Dyno results Eric. . I think it’ll make 60+ hp on your 540 over the current heads. I’ve got Tony Mamo ported 357 AFR’s with a 2.350 valve on my 582 that flow a little better than the 385’s..
Question, on a 540 BBC would you prefer a light titanium intake valve verse a heavier by 64 grams valve or a heavy & bigger 2.350 valve over a 2.300 titanium valve size? If you could only choose one or the other? 😃
With the badass work you do with the dragon slayer small block heads, have you done any with the big block dragon slayers? Would love to see some real world numbers before I send mine into you to work over.
@@B.Fam.RacingI’m not a fan of the bbc dragon slayers. Even though they are a new head they are just rebranded old designs that aren’t that good compared to more modern stuff.
@@WeingartnerRacing Yeah we’re kind of the black sheep of the big 3 not much after market in comparison with the other 2. About to rip my motor out and do a refresh depending on the condition of the head potentially more work than a port. Valve seats are notoriously bad for these and it’s missing so we will see. I have a hellcat. Waiting for me is not an issue, I’m more about quality than speed. If you’re the go to guy waiting is to be expected. I’m in no rush I’m doing this myself just wanted to find out so when the time comes I have a guy. Thank you sir for your time, much respect! I’ll be in touch.
Are these "Enforcers?" I took your advice and bought Brodix BRX AND 1450 CFM Dominator. Should I get the next higher Dominator 1550 cfm ,1650 cfm What do you think? I am running all N/A. on e85,
@WeingartnerRacing bout damn time a big Corp took a stance. Speedmaster is junk. Hit or miss and more bad reviews than good ones. I almost bought there top end package 📦 for my big block chevy.
Hey Eric, Tim here, what a KILLER set of BBC heads from AFR.....great #'s, and i'm with u on the exhaust backin up a bit......i'd give it a whirl as is, ur spring choice is 100% on the money!!!....REDUCE valvetrain weight, WHENEVER you can!!!!........one last thing, un-related, when ya can, give us a Bishop swim update......i've followed so long i feel i know all about it now....haha.......or make a sep vid......just curious......GREAT set of heads, and losing a point in squeeze, but gaining over 40 cfm, the cfm will win!!!....PEACE to you my brother!!
Summit has done me well and I will also do business with them until they dont. Kudos summit and you too
Kudos to Summit. I saw that story on Facebook and watched the original guy's video. Jegs, you are now on the clock. You're selling them too, I'm sure.
I can't wait to see those run! Numbers are almost the same as the 345's you did for me. I learned the hard way purchasing pro comp heads . Glad to see Summit not supporting the overseas crap. Eric thank you again for all you do and you willingness to help.
Hat off to Summit Racing. Good job for the update on this problem. I seen the video right after it come out. Very happy for that Guy !
Wow !! Kudos to Summit !!.. Classy move by them in my opinion. 🍻
BTW, awesome job SUMMIT!!!
Great job summit racing 🏁
Finally a stand up move by Summit
Nice can't wait for the test

I usually don’t measure them
i have a pair of these on a 555 with a tunnel ram. I'm real happy with them.
I bet the AFR385's will make more HP & Torque across the board. I'm excited to see your test results.
I hope
It's great looking on summit and not have to worry about filtering out speed master or pro comp immediately when looking at parts

i have the 1.8 scorpion intake race rockers on mine. I like them more than the comp.
Dang that's cool summit stood up against bad companies
I ordered SBF head studs on a Friday at 8am ( good friday ) They showed Saturday afternoon.
Can you port my iron heads?😂😂😂
I've asked, he doesn't do iron

Super interested in the oil test. Are you doing different pans? Like right side kickout vs. no kickout?
Just a very expensive pan

I would like to see it break 900hp
@@WeingartnerRacing it will easily clear 920+ hp with the SV2 intake.
Question, on a 540 BBC would you prefer a light titanium intake valve verse a heavier by 64 grams valve or a heavy & bigger 2.350 valve over a 2.300 titanium valve size? If you could only choose one or the other? 😃
2.350 titanium
What 1.8 BBC rockers do you want to get for your test mule?
Another set of comp ultra xd. This way it’s not rocker design that might be change power more than ratio.
Now Jeg's needs to step up to the plate and do the same thing.
The should have.
Are you able to measure the BMEP of the long ports vs the short ports?
No

@@WeingartnerRacing damn, that sucks. I’ve been told so many good things about them, especially when compared to old ported bb2’s….
@@B.Fam.Racingshould have asked me. They are essentially ported versions of the bb2 line.
Do you do hemi stuff. For gen 3 hemi?
I can but nobody asks or wants to wait.

Did you buy from me.
What's the best heads for a 402 big block chevy?
Depends on what pistons you have. Do you have pistons for closed or open chamber heads?
Afr 265
@WeingartnerRacing thank you man and nah you're not mean, just gotta be real with folks these days. It needs to make a come back👍👍

Ive seen the broader transmission valve body story. The fake counterfeit valve body was locking up in third. So don’t buy fake stuff!!
So you like free stuff but won’t give free advice 😳
Bingo. I mean besides the hours of videos on UA-cam.
