1970 440 Choke Cup Gasket

Apparently I need one for the 1970 intake manifold, but they are *gasp* $55!

Looks like a composite, like an exhaust manifold gasket, can I just make one or is this special? Without it, the whole inside chamber of the intake is exposed.

Any suggestions without spending 55 times what this thing is worth?
