Don't put a gasket in there! The Super Tiger Gasket only lasts about 10 seconds in spite of it being made from Kevlar gasket material.

Clean up the mating surfaces real good and slap it togehter with some lock washers on the screws. You may use a thin layer of the red high temp silicone on the joint if you want to but most people run with nothing in the joint. Some others have made aluminum gaskets from pop cans. You can cut them out with a pocket knife and punch the holes with an ice pick or awl.

Enjoy
