I like to use the street alloy, not the looser 2616 alloy tsk, version of any brand pistons on all of my motors. Ross does not make that tighter(edited) alloy so I stop using them down I believe all of the Icon brand BB Mopar pistons are the tighter alloy up I have used them in several motors now thumbs
