When I did mine I was told to machine the flywheel ( I don’t think it cost much it was like machining brake drums or rotors it has a stamp on it indicating the minimum thickness I think ) I would clean it up by hand with some emery cloth and see how it looks you would be able to see better if it has hardened spots or other imperfections from the clutch spinning and heating it up if it cleans up good I personally would leave it but I am no pro .Let’s see what others think
