Re: SBP Exhaust Mount
OK just a couple of things when dealing with either the SBP aluminum gasket or the Manic Copper gasket. Yes both copper and aluminum are soft and can conform to some irregularity but they cannot seal without smooth mating surfaces. Both the exhaust header and engine port mating surfaces have to be smooth and flat. If you don't want to take the time to remove the exhaust port studs and file everything down flat then you can use some hi temp RTV to seal it up. That should solve your problem.
