70 225 exhst ? please

Are you looking for the gasket that goes between the intake and exhaust manifolds? The stock metal one is available from most any parts store as part of the manifold gasket kit or you can get one at any Dodge/Chrysler dealer. Pentastar Performance in Australia has a composite gasket available as well that seals on the first try and won't blow out. It took them a week to get one to me, and that is pretty good considering that we are usually 3 days behind on sunshine. FWIW, Pentastar refers to them as hotbox gaskets. Hope this helps.
