Cometic MLS head gasket for Chevrolet Gen‑1 Small Block V8 with a 4.200" bore and .036" compressed thickness with full steam holes. It seals high‑output engines without sealants and suits aluminum or cast‑iron block pairings. Made from multiple embossed stainless steel layers with Viton‑coated outer faces and an uncoated shim core. The multilayer construction rebounds under load, resists corrosion, reduces clamp load and evens sealing pressure around the bore.
