Cometic's MLS head gasket for Chevrolet Gen-1 Small Block V8 (4.060" bore, .023" compressed thickness) uses multiple embossed stainless steel layers with Viton-coated outer layers and an uncoated stainless center shim. This multi-layer design provides strong sealing for high-output engines without additional sealants, resists corrosion, rebounds under load and helps distribute clamp forces to reduce bore distortion.
