Putting on a new valve cover gasket on my new to me 94 cruiser. Ran into a potential issue with the removal of the half moon head cutouts. I was delicate with their removal, however, upon inspection noticed the driver's side half moon was missing sections of the inside lip. Used a section of tshirt to not mar it. Did not hear a tink or anything upon removal. No debris in the the little pocket under the distributor shaft. This still has me pretty worried. Any thought or guidance? Thanks in advance!
