FWIW my "dry" Jap import A14 H72 head has a 2.5mm deep x 76mm diameter counterbore.

The compression ratio is two parts: CCs of combustion chamber (cylinder head) and CCs of piston dish (in pistons).

The H72 as used in USA with dished pistons is medium compression ratio. But the CC of the head isn't extremely large.

H72 is also a casting number. There may be several different heads made from H72 casting.

just wondering if anybody knows if the h72 head is actually a low comp head. The wiki says its not but i thought any of the 360 degree chamber heads are low comp.
