At a guess you will defiantly need forged pistons (not cast) and a metal head gasket with ARP studs. As I said I'm no expert put I think the stock pistons are forged, not sure what BHP they can handle.

Why have u done the head gasket repair so much i though at soon as a MHG was installed and Torqued down with ARP studs the problem was fixed and wouldn't happen again. I'm pretty sure the pistons on a stock 7M-GTE are forged.
