Is it smart???

Ahhh see the thick dome makes sense. I have a set of KB280's which have a very thick dome as well. The idea of the thick dome is to machine it for proper quench,so instead I was thinking machine it for a turbo app,but leave it plenty thick. If necessary adjust the comp down with thick head gaskets and,tada! Turbo pistons on the cheap.

Can you tell me exactly how thick of a piston top we're talking about?
