3rd redo of installing the super six manifolds....help with gaskets

I did it like Krazykuda said. Yes, you need that 3-hole metal piece. Make sure you have it right side up, and that the heat riser flap doesn't jam on it. My other hint is to use Hylomar sealer on both sides of the gasket. Hylomar never sets up -- it stays fluid, which lets the manifolds expand and contract without tearing the gasket or losing seal. Be very systematic about torquing the manifold nuts -- I did it in 25 in/lb increments. Remember, it's only 10 ft/lb (120 in/lb) torque. Overtorquing does not help it seal.

Oh, and this last time, I found a great tool for dealing with the two center bottom nuts, that are kind of behind the exhaust downspout. My brother gave me a very long and extremely thin vintage 3/8 extension -- it's about 12 inches long, and barely bigger in diameter than a 1/4 extension, but it's hardened steel. It can reach straight in where before I was using a u-joint with two 3/8 extensions, or a wobble socket.
