    There's a metal "gasket" that's called the valley pan below the intake manifolds that seals oil in the lifter valley and seals the intake manifold to the heads. Regular carb gasket under the carb.

    I hope so as well. I still reccomend against the autozone carb. You will likely need to tune it, most off the shelf carbs are designed for the mainstream Chevy and Ford small blocks. On a Cadillac Big Block the carb will see a much more "sharp" vacuum signal. I can almost guarantee it will run rich out of the box.
