Clearance PV on ETP 5.3 heads? Have a 98 camaro Z28 M6 with the torquer V.2. Just bought some 5.3 ETP heads will they clear the piston? PV clearance problems? ANd will they bolt right up with no problems? Thanks

Sorry to tell you that the 2.055 valves will not clear the torquer V2 on a 112.
Piston flycut is necessary.
I had 5.3 heads, unmilled with stock gasket and the V2 cam on a 113+0 to clear the 2.04 valves.
I wanted the 112+0 but PTV was too tight and contact likely.
