the conrods are the same in all 220 petrol, some of them MAY be rifle drilled( doesnt matter).. the piston are nearly the same height.. my diff the comp area in the middle ...disk depth...

The 7a pistons are a larger dia and, most importantly, cast not forged. I am not sure about the height either.
