I am considering these… [http://www.livernoismotorsports.com/product.phtml?p=1351](http://www.livernoismotorsports.com/product.phtml?p=1351) i can get a good deal on a set, everything i have read claims they make good power, even comparable to the top dollar aftermarket heads :gotme: ---

Why not spend a lil extra and get a different cam that matches those heads better? Its all in the combination anyways… ---

i was debating on that as well,a cam that is purpose matched to a set of heads… a different cam is what? $350? ---

heads arn’t going to make a night and day difference like the bottle is… I would research good fast 90/90 heads/cam combos…no reason you can’t be 450+ rwhp and gain a lot of torque…obviously with a good tune. ---

these are pretty peaky. the midrange intake is kinda weak and the full exhaust even more-so. for the money they aren’t too bad, but i’d hang on to your bank for now. theres more to a head than flow numbers too… velocity ---

i knew you would want to killl me for considering anything besides AFR’s Bill 😃 There are a few people on Ls1 tech that were posting up dyno sheets of +45- 50 ish rwhp with these heads… if i could pick them up for say… a grand, not a bad choice? ---

no not at all… a good head is a good head. no two ways about it. what are these guys adding 50rwhp with just these heads added running besides these? theres obviously a lot more to this than adding the “bestest” of each kind of part. especially in an NA setup, the COMBO needs to work in unison not saying this wouldn’t make a nice combo, just adding some constructive criticism ---

the one guy i talked to had these heads on his 2004 GTO… 224/224 cam FAST 90 full exhaust etc and claims he went from 358rwhp - 406rhp with just the head swap. ---

even if that is the case, a run of the mill 224 cam is wayyy off the mark from what your grind is. apples and oranges ---
