I never had a gasket fall apart. I suggest new studs, use brass nuts, and locktite. Retighten nuts after an initial warm up period and then again a month later.

I am having a tough time keeping the donut gasket between the manifold and the exhaust pipe from disintegrating. After installation, it takes about 3-4 months of very little driving and they start leaking again. I have been told that there are metal gaskets (poss copper?) and regular donut gaskets with a metal tube insert that helps the heat/exhaust flow through with less stress to the donut. I have not seen anything like what I am describing and wondered if there was someone out there that had some experience with this problem that they could share. Thanks, Ed 70 Chevelle SS Convertible
