Cometic MLS cylinder head gasket for GM Gen-V/VI Big Block V8, intended for a 4.320 in bore with a 0.051 in nominal thickness to provide consistent sealing. Multiple embossed stainless layers are coated with Viton on both sides and a variable uncoated shim layer controls thickness. Compressed operating thickness is 0.051 in. The multi-layer construction resists corrosion and shear, conforms load across the sealing area, and lowers clamp load needs without requiring sealants.
