    Only thing I can see is H579P STD stamped in top of the piston.

    I hope you running stock boost on that engine. That's a Speed Pro hypereutectic piston in there, so that engine has been apart before. Don't turn up the boost, that thing is a grenade waiting to go off.... Those pistons don't play nice with boost unless your tune is absolutely perfect. Then your still gambling...
