GM Performance Valve Covers
I am making a valve cover uprgrade, using the cast aluminum GM performance valve covers. I would like some info on how these valve covers get fastened. Studs do not seem to work on the three top holes on the intake side. I can not get a nut on the stud. Any thoughts? Someone with a 572 crate engine tell me what GM used. thanks
