no disrespect never really messed with rb engines much but is this all the flow you can get from a cnc head? I have ported big block chevy stock 990 heads that flow a lot more than this. the lack of parts for mopars is a joke
Mopar doesn’t really offer anything stock with a 325cc intake runner before porting. You should start a post of your own and tell us about them on some “Chevy site”.
