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.

@ heads shaved .001". That's one thousandth of an inch.

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.

You have tons of room.
Are you sure about the .001" milling. Maybe you mean .010" because doing .001" is totally pointless.

And probably hard. lol

I would think so. Trying to remove .001" without some kind of tool or cutter "bounce" would be hard.

About all .001 would do is make them shiny again... Even at .010 you have plenty of room

Lift is not the only consideration. Cam timing events determine how long that lift dangles the valve in front of the piston.
