Cometic MLS head gasket for Chevrolet Gen‑1 Small Block V8 engines (4.165-inch bore) with 18° or 23° heads, round bore, with steam holes and compressed operating thickness of 0.070 in. Multiple embossed stainless steel layers form the MLS design; outer faces are Viton-coated and the center shim is uncoated stainless. It requires no sealants, suits aluminum-to-aluminum or aluminum-to-iron pairings, resists corrosion, distributes clamp load to reduce bore distortion, and benefits from AMP embossing and Viton heat resistance to 250°C (482°F).
