Lot of BS on using gaskets on the exhaust manifolds. Yes, Ford did not use them. However, things get changed around, the disparate parts do not always fit precisely. Especially things that go through hot and cold cycles all the time. I use gaskets on the exhaust manifolds on my Y's. Never broke a manifold. Have to be careful when tightening them down, in a sequence like doing a cylinder head or an intake manifold. Start from the middle and go out. Don't tighten them up full bore the first time. Do it in steps.
