Cometic's MLS head gasket for Chevrolet Gen-1 Small Block V8 (4.060" bore, .045" compressed thickness) is built from multiple embossed stainless steel layers with Viton-coated outer faces and an uncoated stainless center shim. The multi-layer steel assembly is designed to seal high-output engines without sealants, resist corrosion, rebound under load and better distribute clamp forces to minimize bore distortion between differing head and block materials.
