The Cometic MLS head gasket for AMC/Jeep 4.0L inline-six (4.000in bore) is a multi-layer stainless steel gasket with embossed outer layers coated in Viton for heat and chemical resistance. Designed for high-output engines, the .086in gasket compresses to 0.098" operating thickness, resists corrosion and rebounding forces between dissimilar head and block materials, and requires no sealants for a durable seal.
