Leaking Valve Cover Gaskets

Aluminum head SB, finned cast aluminum valve covers, 5/16 cork/rubber gaskets. I can’t keep SS acorn nuts snug on SS studs. Seems every heat cycle, I have to retighten. I can’t tell if studs loosen in head, or nuts loosen onstuds.

Blue loctite is your friend.
Second thought is try not to use SS to SS it will pick up and gall.
