I've been researching this since I replaced my carb gasket on Friday. The preferred gasket is about 1/4" thick with an open center. Fel-Pro 60249 is what I used.

You will need to look at the intake manifold. I heard there are some manifolds that have a heat vent port that require the metal gasket and a standard gasket on the top and bottom of the metal gasket.
