It would have to look like an old TRW blower piston, with a dome at the quench pad end and a waay below deck crown level on the other end. Even at that, by the time You fill/mill the chamber to give a gasket plane surface for an effective squish to accelerate the burn,..the squeeze will be up there. The long-rod/Wiseco piston combo will be very high if it's at -0- deck with said modded head. I honestly don't know how much the compact chamber will allow w/a fast burn because I don't know anybody that's run an effective squish slanty.
