Looks nice.


It looks like the only difference between the two is that the deck is thicker under the reverse dome on this style of piston. I was told they could not carve a 22cc reverse dome on a standard flat top, as it would leave too little deck thickness.


Yes, of course it is forged to allow adequate thickness. I would still call it a dish.

There are pistons out there that actually step-up opposite the spark plug that also have a dish. Those I would call a reverse dome.
