    I'm rejuvenating the engine bay in my 76 Riv and seem to have a small valve cover leak. My blue valve covers are very rusty, so I plan to replace them with some nice (stock-looking) chrome ones, along with a replacement chrome air cleaner lid and a few other things. All new aluminum AC components are coming too.

    What's the best valve cover gaskets? Cork or rubber? Who sells the best ones?

    I guess its just a matter of opinion or preference. I prefer cork myself with a skim coat of Permatex Ultra black on both sides.

    Cork. And maybe rough up the chrome mating surface of the valve cover.

    TA has cork in different thicknesses the 1/4in works well for sealing issues and uses a more dense material , iirc the stock bolts still work fine
