Nice writeup & pic's! FYI the oe cam cover plug is a 5mm allen so yours has been removed before.
Thank you! The oil plug was the same way, but it would make sense that it has been replaced before. I can't think of a good reason to change the cam cover plug. It didn't have the appearance of a replaced part as far as dirt and patina, so if it was done it was a long time ago.
