Int/Exh Manifold sealer

kamzack

Is there a sealer that can be used in conjunction with gasket between intake and exhaust manifolds on a 254? The intake is aluminum and when fired for the first time it leaked at this point. Owner had deck surface milled, so don't know if this has affected clearence.

If both surfaces were milled, then you would have to use 2 gaskets and a good sealer. Another way is have the exhaust manifold milled where it sets on the block. It must be done so that it stays straight front to rear. Walt.
