Cometic MLS head gasket for Chevrolet Gen‑1 Small Block V8 with a 4.165" bore and .040" compressed thickness with full steam holes. It provides robust sealing for high‑output engines without the need for sealants and suits aluminum or cast‑iron block setups. Made from embossed stainless steel layers topped with Viton coating on both outer faces and an uncoated shim center. The multilayer design rebounds, resists corrosion and evens clamp load across the sealing area.
