  • Exhaust Manifold Gasket

    Has anyone used the high tech type of manifold gaskets made out of thick 1/8" carbon material on a 430? These are supposed to make up for any low spots.

    The original type thin sheet metal gaskets seem to leak very slightly, and I have a chance to switch them now. The Fel-Pro gaskets are 1/2 asbestos and 1/2 metal, but I've never used those either.

    Can anyone give some recommendations on what has worked or not worked?

    Thanks

      No. That would have meant removing 4 studs from each manifold. The shop didn't really want to get involved in broken manifold studs, and I kind of agree.

      They weren't leaking when I brought the engine in. All that I hear now is a slight leak from the small head pipe gasket itself.

      These are the hi-tech carbon ones that I found for the 430. I think they are like the No-Blow, but Im not sure.

      They say "Guaranteed not to leak". http://www.remflex.com/exclusive_features.htm

        Heres a re-post from a thread by Alaxender,
        If you do a search on this message board, you will see this topic has come up at least a dozen times before. The exhaust manifolds tend to warp and corrode over time, preventing a gasketless seal against the head.

        Re-posted from an earlier thread:

        I have also had problems chronically with leaky exhaust manifold gaskets. They always manage to leak at the mating surface to the head. I have also tried header type gaskets, which seal better than the stock gaskets, but tend to blow after they dry and harden. The best solution I found is to use copper exhaust gaskets. These can be obtained for the big block Ford from JC Whitney http://www.jcwhitney.com/ . They are SCE Pro Copper gaskets, JC Whitney part #81DL4478W. They are listed as fitting FE engines from 61-71, but they do fit the 58-60, since they fit on my 1959. They will never leak or blow. After about a year of oxidation, they have the almost the same color as stock gaskets.
        Bob's Bird House http://www.bobsbirdhouse.com/ also sells a grey colored thick high tech gasket set. It worked for a friend's Squarebird.

          I saw that, and checked Bobs B'House and Whitney --

          Not for the 430. These are the only ones that I found so far.
