I have a custom made header to muffler flange setup. I am having problems with blowing out gaskets. I have looked at the surfaces and they seem to be relatively close to meeting flush. I assumed a gasket would seal any slight deformities. I used Mr Gasket white asbestos material to make the gaskets. The problem is once they get hot they become brittle. Does any one know of anyone that sells aluminum/asbestos bulk material of of any permatex type material that I might be able to use. Or any other ideas.

Thanks:
