changed out the manifold today and was told by a friend to use ultra black silicone by permatex in place of the gasket put down a 1/4 inch bead let it sit for a couple of hours then installed it and no leaks he said a fellow that builds headers told him about it and that's all he uses I'm sold also put some where the donut sits on manifold and pipe

Frank,

Have you had problems in the past with gaskets for the y block exhaust manifolds?

The old-school fellow at the machine shop who rebuilt my 292 told me to not use exh gaskets so the manifold ears don't crack.

I use the gaskets but put anti seize on the shiney surface against the head. No issues with leaks or broken ears (FEs).
