It didnt take long to realize the chrome was not going to clean up. It appears that they have been wiped with Scotch-Brite and there was some mild spotting from rust.
Looking inside I saw that they had been pulled off of a used motor and "sorta" cleaned up before installing them on this 305 HO. The left over grunge bothered me, so I decided to clean them up in my blasting cabinet.
Before committing to keep them, I checked the mounting surface with a straight edge and they were all true. Despite the appearance, these were actually a quality set of chrome covers. Committed to reusing them on my build I media blasted all of the internal grunge then hosed them down with brake cleaner.
Prepping chrome for paint is not an easy task. I cleaned the chrome in the blasting cabinet, then hit it with 150#grit to give the primer something to bite on. Once I had the whole surface sanded I came back with Scoth-Brite and brake cleaner to ensure a oil free surface.
After a blew them clean inside and out once more, I laid down a few coats of sandable primer. When this cures, I plan to wet sand and test the adhesion. If it sticks well, I will add a color coat.

I'm so glad to see you redoing those valve covers. I was worried you were going 90s chrome on us! Haha just kidding
