AFR205 or ET215 Been searching for awhile and have a hard time deciding on what head to get. Everbody seems to like both. But what will be the best set up from the people htat have tried first hand. This is what I already have, Ls6 intake, asp pulley, 4.10 gears, lid, long tubes, and ported tb. They seem to be around the same price. Also my bottom end is stock. Maybe in the near future I may upgrade to bigger CI. But for now the 346 will do. Also i'm kind of stuck on the f14 cam to go along with the setup. if somebody thinks differently please speak up. Thanks

I don't have my setup completed yet but I have everything ordered and I'm using an F13 cam. I went with the AFR 205's over the ETP 215's just because nobody has the ETP's and people have been waiting for weeks to get theirs. I think either head will provide similar results if they are setup for the same compression IMO, but who knows (not enough data on the ETP's yet). One thing I like about the ETP's is that I would not have to flycut to run 11.25:1 compression with the F13 and that is what has to be done with the AFR's.

That f14 probably will be tight on your p-v clearances, also remember that a mechanical over-rev will bend valves in a STOCK motor and there is nothing to remedy that other than good shifting. I bent 8 valves on my stock 2000 c5 so I know first hand about it. Also, the best valve spring money can buy is never a bad thing.

I hit 455 rwhp, 421 rwtq, with 90/90 set-up! Also remember, check your valve clearances with EVERY combination no matter what cam you use. Tony Mamo should hire me to be AFR's pr guy, that is how much I like AFR's heads. By the way, I am running stock MLS gaskets.

Both are great heads, the AFR have more then proved them self as a top performer.
ET is new, but has all the right stuff to make it one of the best LS heads on the market, also the ET 215 will give more PTV with more compression then any other head out there right now.
I also like the FM14 cam, either head will make a killer set-up.
