FYI, even if you want some great flowing heads for a SBC it will cost you $1200. min to $2200.00 ported, I know you see them cnc ported advertized flowing 300+ some odd cfm ,but a lot of Co BS in there advertizement.
Chevy v-6 heads are more popular than our inline Chevy's & they will set you back $2200.00 min w/porting.
