common 318/two-barrel valve sizes of 1.78/1.50-inch and in stock trim flow about 135 cfm stock on the intake side

The fully ported heads with larger valves installed showed an intake flow improvement of nearly 60 percent to a respectable 215 cfm at a peak of 0.500 lift.

Its a stretch but the heads "can" be modified.
not sure its worth it if you pay someone for the porting...
