I believe the intake port volume on all D-port heads were essentailly the same, so would flow similar numbers with tehe same size valves. Just combustion chamber cc's varied.

Dennis,the '70 350 heads are "11" casting # and i think are around a 75cc with press-in studs.I ran a 068 cam in my,it was a little lazy with a 2.78 gear but after it was rolling it pull pretty good. It outran alot of pesky lil hondas on the highway.
