what pistons do I need????

OK here the deal, I have a 97 gt with pi swap and WAS using comp 270s until we found out it was having ptv. Now I need new pistons. I called comp but they couldn't tell me much as far as what pistons to get. So I wanted to ask on here, does anyone know what pistons I need? How much of a dish and anything else I need to know. I would appriciate any help. Thanx

Might not help much, but I read a post on another forum where it was mentioned that Diamond makes a good piston that comes with valve reliefs. I am pretty sure that was on a flat top design...no dish, which is what you would be looking for I guess since you are N/A. Hope that gives you a lead to pursue.

I think the issue is primarily on the 99 and up cars because of the .550 lift combined with the 5* of advance ground into the cam by CC and the amount of duration in the cam. I have read where one guy had issues with the 268AH cam as well on a 99. I would seriously doubt that the NPI heads have a PTV issue with the Comp Cams since they run only .500 lift.
