I couldn't find a good Felpro gasket locally for my Edelbrock Performer manifold. I did find a Mr. Gasket (for Chev. 262 - 400) at AutoZone that I believe to be good, but it has one problem...there is no provision at all for the heat crossover.
I don't mind the block-off, but my concern is that I'm going to get this thing on, and 100 miles down the road the gasket is going to fail. My other set had a metal insert. This gasket is as though there was no heat passage.
