Wouldn't be the other way around? The less air flow though the head, ie lower volumetric effeciency, the less air would be compressed into the combustion chamber? Or are we talking at cross purposes?
Anyway, the design of the head/piston/combustion chamber has a huge effect on this with lots of potential "Got Yas!". With things happening pretty quick in the combustion chamber hot spots caused by irregularities in air flow, matrail differences, rough spots or jagged edges can make or break performance and pistons (at least the break part).
