Steel Crome Small Block Chevy (straight across bolt holes) Valve Covers $25.+ $15. shipping. You can see in pictures I'm pointing to a small rusty area on one valve cover & on the other valve cover it has a dent from maybe the alternator? I DON'T think these are factory GM Valve Covers? They are heavy thick steel valve covers made around the mid 1970's ? Open to offers plus shipping.
