The Cometic MLS cylinder head gasket for Chevrolet Gen‑1 Small Block V8 (4.165" bore, 0.120" compressed thickness) is made for round‑bore, 18/23° heads and supplied with steam holes. Its layered stainless construction features embossed, Viton/AMP-coated outer faces and a variable uncoated shim center for thickness control. Designed to seal mixed-metal head/block combinations without sealants, it rebounds to resist corrosion and reduces clamp load effects on bore geometry.
