I'm fed up with these valve covers I have, all they do is leak no matter what I do. Tried Moroso and Superformance gaskets, tried these billet spacers someone recommended, tried new quality bolts. They still leak and I'm tired of it. Yes they are some Chinese RPC covers and I'm ready to buy some good quality valve covers. Can people with experience not your opinion from a picture offer up some choices? I'm about ready to but those expensive Moroso valve covers!!!
