Manifold gaskets

[hangarb7]

That is interesting. So on the copper gasket, the side that has the copper sticking out (like a thin bushing) goes into the manifold casting and not the block?

And the high temp exhaust coating, the last time I bought that stuff, it was like a thick paste, gritty almost like with sand in it. Is that what you are talking about ?

Thanks,
