KB pistons you can BUY with 6-15CC dish.They are CAST, WITH Silicon. They put WAY less wear on your block.
and they LAST. They typically weigh less than Forged as well, which is good.
>>Although not as strong as forged pistons, hypereutectic pistons offer increased strength that raises piston reliability at a lower cost. Hypereutectic pistons also don't experience as much thermal expansion as forged units, which means they can be mated to their respective cylinder bores with tighter tolerances.They have more Silicon than Stock cast piston
which decreases cylinder wear.
DONT , DO NOT, have the engine built ( Again) and have it sit for years ( body shops are booked way up right now)
A replacement piston with 4 valve reliefs (6-7 cc) , or a small dish)and thicker than stock head gasket will be fine on pump gas
