nothing was milled on the heads. i was going to just line the cam up dot to dot and see if it would spin without hitting i was just wondering if anybody had done this without flycutting . If I have to flycut is it able to be done in the car i dont want to pull the motor

even if it spins cold things happen when it gets hot and parts expand, remember that. It will be close but it *should* clear if everything is correct. Personally if you dont mind flycutting i would, and run a smaller head gasket for more compression while you have the heads off. It will help your car quite a bit because of the size of that cam.

Yes...they make a tool for cutting the pistons in the car. You have to pull the head, but not the engine. There are actually threads here on the site that discuss it. Tool is about $100 for a good one if I recall. I may even have a brand new one.

That is a horrible way to determine PTV clearance. You could freewheel with .010 clearance...but it won't run with that...for long anyway. Spend the time to do it right...you won't regret it.
