State-of-the-art gaskets is what Cometic has been doing since its inception in 1989. This comes from their dedication to constructing gaskets for the most demanding race circuits like AMA and NASCAR. Todays lightweight engines are producing more horsepower, higher cylinder pressure, clamp load and extreme temperatures. Cometics commitment is to provide innovative, quality gaskets while maximizing your engines power and performance. Cometic meets the needs of each specific gasket by using materials to match. Even the basic top end gasket kit features different materials for each gasket. The head gasket is constructed from non-asbestos, flexible graphite that is laminated to a stainless steel core. The manifold and base gaskets are constructed from non-asbestos nitride rubber-bound fiber. Cometic also includes copper gaskets where needed. Cometic designs and builds their gaskets in the U.S.A. This kit contains the following components: 1 - Inner head O-ring. 1 - Outer head O-ring. 5 - Head crush washers. 2 - Base gaskets. 1 - Intake gasket. 1 - Exhaust gasket.
