Use the one piece silicone rubber gasket from Moroso. They are great gskts. the bolt holes have a metal insert so you don't crush the gasket out and it has a dip stick provision that is closed off on the inside so you can leave the excess hang, can't believe I said that, or cut it off with no leak. A little expensive but believe me after you use one you won't use another pan gskt.
Fel-Pro has the same type of gasket too. Silicone with the "crush sleeves". I'll never use another cork gasket unless it's my only option.
