    Here are the correct 1970-71 manifolds. It doesn't matter what year your block or heads are, they are going to fit the same way.

    And are you running Mopar Performance Valve Covers? That's our issue. We can't find anyone running HP manifolds with Mopar Performance valve covers. We know they will fit clearance wise with stock valve covers but we have the MP valve covers which are a little bigger. Thoughts on this???

    I'm sure they may be a little bigger, and it may be a little closer, but they'll still fit.

    What type of exhaust manifold gaskets? Fel pro?

    Ditch them and get copper gaskets.
    I went with SCE gaskets and they are working great.

    Also a good idea to Ceramic coat the manifolds.

    Fel-Pro, Moroso and the latest victim? The Carbon-X gaskets.
    Who makes the copper gaskets? (We're talking valve cover gaskets right?)

    Can't afford to remove the manifolds- so it'll have to be brush-applied. Any product you can recommend?

    Actually, the Moroso ones I tried were those. Steel core-Rubber.
    Melted right away on the back corner area.
