The Cometic MLS head gasket for GM Gen-V/VI Big Block V8 with a 4.375in bore and .070in nominal thickness offers robust sealing for high-output big-block engines. Built from multiple embossed stainless steel layers with Viton-coated outer faces and an uncoated center shim, it resists corrosion and rebounds under load. The MLS design helps conform load distribution across the sealing area, lowers required clamp load, and provides reliable sealing without additional sealants.
