If there is a good fit between parts a gasket is not necessarily needed. But more often than not the parts dotn fit tightly together. But that doesnt mean you have to use shelf gaskets. You can use a good high temp rtv when you put them on to seal up any leaks. I know one guy who told me they cant get anything else to seal up on their aluminum headed motors except the RTV.

Get the Felpro performance gaskets or copper pieces. I've reused the Felpro performance ones 3 or 4 times, sometime more, before they burnt through. They're the gaskets with the steel 1 piece core. The paper ones or 3 piece ones in gasket sets suck. They don't even last long the first time they're installed.

My engine builder told me NOT to use gaskets. There isnt a need for them if your manifolds arent warped. He says it helps pull heat away from the head, And a gasket will "isolate" it. If it helps dissapate SOME heat, Ill do it.

Thats how I always run mine, and they came from the factory like that.(like litteb24f said!)

wizzard,

I like your thought process on the carbon seal! We used to induce rust on our kart engines fly wheel when we lapped it and set the timing. My engine builder told me he never had such a hard time getting the fly wheel off our engines. Never skipped timing though!
