Cometic MLS cylinder head gasket for GM Gen-V/VI Big Block V8, sized to a 4.320 in bore with a 0.080 in nominal thickness and a compressed operating thickness listed at 0.036 in. The gasket uses embossed outer stainless layers coated with Viton and an uncoated center shim to control sealing height. MLS construction provides rebound and corrosion resistance, handles mixed-material shear, conforms load distribution, and lowers clamp load without the need for sealants.
