    M20 Exhaust Manifold Gaskets w/o Heatshields

    Been having an exhaust leak on these cheap ebay headers, so I was looking to double up the gaskets. Can't seem to find a gasket without the heat sheild attached. I already have a new set with shields just need somthing to sandwich. Ebay has a set that comes with a flange for turbo applications, but I don't need the flange. Anybody know who sells these?

    Thanks in Advance

    Double the gasket?

    Isn't that a big no-no....

      To an extent but I can't see the downside. Its easier that cutting off the headers and re-welding stock manifolds back on.

        As far as I know, only heat shield exhaust gaskets are available. A pair of tin snips can be used to convert the standard gasket to just a gasket by cutting off the heat shield. But a better solution would be to replace the piece junk that you have now with quality headers.

          I made mine from Mr. Gasket exhaust gasket stock (steel-core graphite version). Took a while, but they work great. After 2 years, I'm still on the first set, and I made spares. Nice to have a sealed header flange, and not have the heat shields in the way.

            double gaskets do not work. re-weld header flanges, if you want to be cheap about it. you can try to sand down the flanges and true them and use copper spray.

              Well I was missing a few studs on the head. Replaced them and got new nut and torqued her down. No more exhaust leak! Thanks for the insight.

                ^ that would definitely cause a leak.

                  ^ they had bolts in them, but I was questioning how well they were actually sealing. It just glad that nightmare is over!
