Small Block Cylinder Heads 'Stock Specs'

Mr. Wild & Crazy,

I agree, used Cylinder heads {cores} will undoubtedly come up with less
Intake Port Volume.

But we have measured a set of old 'new stock' #2843675 Cylinder Heads that
were from 1968, still boxed.

With 'untouched' Valve Seats and 'new' Mopar Intake Valves installed,

We came up with an average of 126.7 CC's {rounded off to 127 CC's}.
