Re: Carburetor Gaskets why so many

TxGoat is correct. Packard used a phenolic spacer about 3/8" or 1 cm thick between the intake manifold and carb base to reduce direct heat transfer. A gasket was installed on either side of the spacer. On some models or carbs they used additional heat control in the form of a sheet metal deflector over the manifold to reduce manifold radiant heat from affecting the carb.

Here is a photo showing a typical installation. Spacer was consistent depending on carb base but the shape and use of the metal shield varied.
