The Cometic MLS head gasket for Chevrolet Gen-1 Small Block V8 (4.060in bore) with a compressed operating thickness of 0.075in is a multi-layer stainless steel gasket designed for high-output engines. Embossed outer layers coated with Viton offer heat-resistant sealing; the uncoated center shim enables precise thickness choices. MLS construction handles the shear created by dissimilar materials, distributes clamp load to limit bore distortion, and seals reliably without sealants.
