What are you guys using for pistons in your windsor motors to have enough PTV clearance for AFR 225's. Im running a 418w 9.5 deck with srp flat tops and they are not even gonna come close to working and there is not enough material in the pistons to cut for the right ptv clearance. My exhaust valve grazes the piston when turning the motor over by hand and only have .020 on the intake. Found this out when we went to check my PTV. Sucks having a brand new set of pistons you cant use!!!
