The "correct" gasket would have four cutouts so that it will fit no matter which way it is installed. You only need one cutout - to fit under the port on the carb. The cutouts don't affect the seal at the insulator to manifold.

I'm sure that others can give you good info re: gaskets.

If it looks like one or two gaskets will elevate your carb to where the throttle rod to the carb will be too short, then ... My uneducated suggestion would be to lap both sides of the insulator with sandpaper glued to a flat surface such as a table saw, jointer, or plate glass. That will make it truly flat so that you will only need a thin gasket(s) to seal.
