302 info:
I flowed the stock 302 head (983 casting)with stock valves and got the following flow numbers:
Intake 175 cfm @ .500 lift(gag,puke,spit)
Exhaust 115 cfm @ .400 lift.

Both the intake and the exhaust leveled out at those lifts and wouldn't flow any better even though I flowed them to .750 lift.

Now I have to figure out how to get more flow or
buy a bigger rubber band for the dragster.
