Cometic MLS cylinder head gasket for GM Gen-V/VI Big Block V8, matched to a 4.320 in bore with a 0.086 in nominal thickness for heavy sealing applications. Constructed from multiple embossed stainless layers coated with Viton on the faces and an uncoated shim center, it resists shearing between heads and blocks. Compressed operating thickness is 0.086 in. The MLS design improves load conformity, offers corrosion resistance and rebound, and reduces clamp load without sealants.
