Are there any differences in the heads of a 350 between 70 and 72? Things such as chamber volume, size of ports. I'm trying to decide whether or not I should use the 70 heads on my 72. Scourge:beer
port sizes are the same, valves are the same, ect. combustion chamber volume is slightly lower on the 70's. 48cc's to probably 50cc's in the 72's. would cost you a fraction of a compression point.
