    Hello, Just wondering if anyone has some flow number for 350 heads, so i can plug them into my desktop dyno 2000. And if possible give them for the larger 1.92 and 1.88 valves, Or if they can just get me some stock number i can play with it from there.

    Thanks for the help in advance

    I would also really like to see the flow numbers of the heads with larger valves installed vs a stock head. How much does head porting affect the flow of these heads? Does not seem to be easy information to obtain as everyone seems to focus on the 455.

    Street/Strip port with oversize valves 220-230 intake & 165-170 exhaust @ around .500 lift. More to be had with competition port, that' s all I can give you.
