Cometic MLS head gasket for Chevrolet Gen‑1 Small Block V8 engines (4.060-inch bore) with 18° or 23° heads, round bore and compressed operating thickness of 0.140 in. Constructed from multiple embossed stainless layers with Viton-coated outer faces and an uncoated stainless center shim, this MLS gasket needs no sealants. It suits aluminum-to-aluminum or aluminum-to-iron setups, resists corrosion, distributes clamp load to reduce bore distortion, and uses AMP embossing plus Viton to improve sealing under heat to 250°C (482°F).
