Default Flycutting piston help

what is the MAX you want to go on flycutting the pistons? is there a certain range? will it harm the piston if you take too much out and spray it?

The key to cutting your pistons is to only cut what you need to get the proper clearance required, I use .050 clearance on my intake and .100 on the exhaust. Any more and you can only make the piston weaker than they already are.
