Cometic MLS cylinder head gasket for Buick Big Block V8 applications (4.312in bore, .027in). Multiple embossed stainless steel layers include Viton-coated outer faces and an uncoated shim layer to meet thickness needs. The MLS design seals aluminum and cast-iron mating surfaces, rebounds under load, resists corrosion, eliminates the need for sealants and helps distribute clamp load to reduce bore distortion in high-output builds.
