it looks like the top one is the low compression ma10 one with the deeper 3.7mm dish, and the next one down is the high comp ma10 one with the smaller 2mm dish but same 26.5m compression height (middle of pin to crown)
incidentally cg,s are 28mm compression height 18mm pin dia :grinning:

the E10S piston could be a good 1mm overbore/high compression option for the CGA :cool:

is there scope for that much of an overbore on the cga then frank? the cg already have pretty thin walls right?
i think 1mm (1/2 a mm off the wall) would be the absolute max ed, the CGA compression height is 26.5, so a 1.5 skim off the crown would leave a 4mm dish, (probably a lot smaller than the CGA very wide 5mm deep bowl/pan shape)
