Cometic's MLS head gasket for Chevrolet Gen-1 Small Block V8 (4.060" bore, .034" compressed thickness) employs multiple embossed stainless steel layers with Viton-coated outer faces for reliable sealing without additional sealants. The uncoated stainless center shim allows thickness variation. MLS construction provides rebound and corrosion resistance while helping conform load distribution and reducing clamp load needs.
