with my 408 at around 8.9cr i can only run about 11psi and thats with prety low timing before i see knock. i dont think you will see 15 without meth or race gas.
prety sure you could make more power on the same fuel with the 6.0 heads. you have plenty of turbo there. i think i would try the 6.0 heads.

Thanks for the advice... Yeah Im think Im going to run the 6.0 heads because I know they flow alot better on the exhaust side plus they will put me at about 8.3-1 CR.
