Anyone have a good Header gasket recommendation for the FE390? Mine keep failing. After removing the headers to take my heads back for repair I'm noticing a blown out place on the back part of the passenger side and on the front part of the drivers side. I recently bought a set of Mr. Gasket header gaskets that were supposed to be thicker and better for header applications but I was a little skeptical of the material used as they seems more papery than I would think a header gasket would be. Anybody had any good experiences with any? I need to get some coming this way while my heads are being repaired. Many thanks in advance.
