i have a 94 TA and it has a comp cam that has .510 lift and i was going to put 1.6 rockers on it but i wanted to make sure the valves dont hit the piston. It has stock pistons and the heads are shaved .001. I dont think they will but i thought i would see if anyone else has put more lift in there car.

In no way are you even close to having issues with PTVC. Duration has a much larger impact on PTV clearance than lift.
I have a zero-decked block, .600" lift, 1.6 rockers with heads milled .020" and have plenty of room to go.
