Cometic's MLS head gasket for Chevrolet Gen-1 Small Block V8 (4.060" bore, .038" compressed thickness) uses multiple embossed stainless steel layers with Viton-coated outer faces to provide robust sealing without sealants. The center shim layer is uncoated stainless steel to allow thickness variation. MLS construction resists corrosion, rebounds under load and helps conform load distribution while reducing clamp load requirements.
