The A14/A15 heads are 31cc
The GX heads are 29cc
The 1980 80HP piston reportedly has larger CC dish than the H95 piston. Unfortunately I don't know the exact number.
Yes, if you are going to mill the block deck, then you can get any compression you want. You can also mill the piston tops too. Even with the same compression ratio, dished pistons will make less power than flat-tops. The H95 dishes are good though since they are a quench design.
From what I understand, a good quench is worth more HP than 0.5 compression increase.
By the way, in the US market, there are many choices for cast pistons. Nissan alone sells 3 different A15 pistons, plus overbore sizes.
