Resurfacing a flywheel?

[Matts30coupe]

Hey there guys. I am in the process of putting my drivetrain back together. Problem is that my flywheel is pitted on the clutch side. I feel I can take off .020” to clean it up.

Question is that how much can I get away with removing? With this throw this out of tolerance? I feel the springs will take up the slack if it’s only a little amount. I rather not burn though my clutch due to it not being a good surface. Anything will help. Thanks all
