You're allowed 2 OEM type gaskets, IF you can find a gasket with a smaller hole in it then go for it! But it's gotta be a GASKET.
The EFI guys are making steel and aluminum plates and putting them between the throttle body and the manifold.

Why would you need 2 gaskets other than to put one on each side of the restrictor plate?

Some carbureted combos like a larger "plenum" under the carb. Some don't.
