Re: uh-oh with gasket maker...?
You'll see that warning on most, if not all silicone based gasket sealers/compounds. I wouldn't rely solely on a gasket maker/sealer but instead would suggest you make a new gasket from the proper gasket material. You auto parts store should have it. I like to use a heavy gasket material on the exhaust side, preferably 1/8" thick and I don't use silicone or any other sealer. Just torque the flange fasteners correctly and retorque once again after the engine has reached operating temperature.
