OK, what type of exhaust header gasket is best? I'm running 8 pounds boost with a ram-horn style header on a 96 miata.

which is best? a three piece metal gasket (like a stock one) or a foam and metal sandwich style gasket?

Thanks!

 

oem/mls

everything else is crap

 

clarification: option two is called an aluminum graphite gasket

 

OK thanks. I currently have a aluminum graphite gasket on the car (it came with the header) and i'm getting a small leak I believe. It sounds almost like a bad lifter, but is coming from the area where the header meets the engine. i was hoping someone would say that I have the wrong gasket.

 

You have the wrong gasket.

 

great thanks! I order an OEM gasket. one more question: do i need to face the header? (like on a bridgeport) i head someone say that all new headers need to be faced.

 

Questions like "should I surface this flange" are always answered with, "hell yeah" on this forum.
