Cometic's MLS head gasket for Chevrolet Gen-1 Small Block V8 (4.060" bore, .056" compressed thickness) features multiple embossed stainless steel layers with Viton-coated outer layers and an uncoated stainless center shim. The multi-layer steel design provides strong sealing for high-output engines, performs without additional sealants, resists corrosion, rebounds under load and helps distribute clamp forces to reduce distortion across differing head and block materials.
