The Cometic MLS head gasket for Chevrolet Mark-IV Big Block V8 applications (4.320in bore, .027 compressed thickness) uses multiple embossed stainless steel layers with Viton-coated outer faces to deliver high sealing performance without sealants. The multilayer construction rebounds under load, resists corrosion, and helps conform load distribution across the sealing area for demanding engines.
