So i need some help figuring out what im doing, I have a 99 cast 6.0 that i am going to build. I also have a pair of 99 camaro heads and im not sure if they will just bolt on or if i need to get different heads. I thought about lq9 heads but not sure if that would be best, i plan on carb set up. I'm a rookie at the ls engine stuff so i need a bit of a guiding light. Thanks.
what happened to the stock 6.0 heads,the lq4 and the lq9 heads are the same casting number 317 i would use these before a ls1 head any dayOriginally Posted by thestanz

The LS1 heads will give a bit more compression but the 317s will flow better. the LS1 heads also have a bit smaller bore possibly creating hot spots in the quench area. Go 317s
I bought the shortblock for 100 bucks and figured i could find some heads, I will go with some 317's if they are that much better. Thanks for the help guys!!
