what is the best flowing head hands down for a fi application with a 106 mm turbo obviously lsx looking for responses! with a say 416 ci or 427 ci roughly.

 

I would say Trickflow... not because I can quote you specific specs, but that I have seen 4-5 1500-2000hp setups all using them. (Even my lowly 1000hp setup uses them)

 

If you are made of money why not All Pro heads?

 

All Pro, ET/Performance Inductions, TF...You're gonna want a 6 bolt setup.

 

All Pro, ETP, and TF are all great heads.

 

AFR's here....

 

Is this a street car??? 106mm is way too much!!!

 

best
All Pro and C5R

great
ET 245
TFS 245
etc

real good
tfs
afr
et
anything else with a thick deck.

Maybe I'm biased I recently picked up some badass C5R heads but unless buisness picks up I won't be using them.

 

AFR doesn't have a 6 bolt offering.

 

ET225s (4 bolt) are working pretty well for me

 

I think that's a wide open question, how much power do you want to make 1800? 2000? 2200?

We've had customers make 1900hp with a 360-370 cfm head, if you want to make 2200+ you'll need a 400+ cfm head, and I would like to see more like 440 cfm.

 

i have a 245 custom etp head right now.it is already a 7 sec camro.it is full racr and want to race it in the lsx shoot out in drag radial class.i am just wndering in general what perople think.i have a cuctom etp 245 head that cary made me with a super victor

 

David Wolfe ran 7.40's with a 350 cfm head and drag radials. Getting the car down the track is where I would spend your money.

 

I dont remember the original poster asking for 6 bolt. Someone recommended 6 bolt..

Peeps have gone 8's with 4 bolt.

 

Come on VINCE they went 6's with AFR Heads

 

Anybody using aftrmrkt LS7 heads.......with the 6 bolts.
What flow numbers are they getting from those heads........
Tony

 

Eh he did say LSx so why wouldnt you go with more the 4 bolts?

 

He said lsx which could mean LSx or LSX. I personally preffer the AFR head to all others for a 4 bolt cathedral port setup. You bolt it on and it performs. No special rockers. No 10" pushrods (that's an exaggeration). No issues with getting to the plugs if you are still running A/C.

Unfortunately, they haven't released a product to compete with the ETP245 and TFS245 and nothing in a 6 bolt.

 

I have ETLS7's going on my 9.5:1 427ci F1R this week.
