Replace the head button...
A pitted head button is due to a bad tune and by sanding/polishing it, will cause your motor to loose compression as well. Your head clearance will be off and most cases the button will not seal with the sleeve properly either... For what $10.00-$15.00 USD, go buy a new head button, run the proper plug/nitro% combination, run a tune pipe more suited to the motor you're running, don't run your motor out of tune/to lean... and you won't have anymore pitted head button issues...
Your motor will run faster, your glow plugs will last longer and your motor will be happy you did...
