Your engine will never know if it's painted or not. Mopar's don't have issues with poor oil drain back. Just sayin'. Clean things up like @moparmat2000 showed above. That will do the trick.
First I ever saw mention of the painting of lifter galleys was from the old P.A.W. catalogs with the various short block offerings, listed in the features. Purely cosmetic, just window dressing and a feel good waste of time.
