Re: Exhaust Manifold Question

Dan, I think those steel gaskets were all that came on them for the factory. They seem to be more of a heat shield for the spark plugs than a gasket. Felpro sells a replacement set if needed. I have the Ford numbers and think the Felpro too if needed. 12-18 ft lbs was factory tq spec with the stock bolt lock tabs. And of course be sure the manifolds/heads have a nice flat surface to seal to. But no gasket other than the tins that I know of on the 64 T. My 390 in the 68 the PO just used lockwashers and they come loose often and leak. I have headers to replace them with though. Hope this helps somewhat.
