Cometic MLS cylinder head gasket for GM Gen-V/VI Big Block V8, sized for a 4.320 in bore with a 0.056 in nominal thickness and a compressed operating thickness listed at 0.036 in. The gasket pairs embossed outer stainless layers coated with Viton and an uncoated center shim to accommodate thickness variation. MLS construction rebounds to resist corrosion and shearing between head and block materials, conforms load distribution, and reduces required clamp load without sealants.
