We are now offering the Cometic line of MLS gaskets. Available for most gas and diesel applications, these are made of a Multi Layer Steel and seal better and hold up to power better than stock replacements. Also, select head gaskets are available with Silver plated Nitrogen filled O rings. No need to machine the head for orings, the Head gasket has them included in the gasket. Pretty cool stuff. You can check them out at www.cometic.com PM or post up questions and prices.
