Cometic MLS head gasket for Chevrolet Gen‑1 Small Block V8 with a 4.060" bore and .030" compressed thickness for 18° or 23° round‑bore heads. It provides sealing for high‑output engines without sealants and fits aluminum‑to‑aluminum or aluminum‑to‑cast‑iron combinations. Made from multiple embossed stainless steel layers with Viton‑coated outer faces and an uncoated shim core. The multilayer construction rebounds, resists corrosion, requires less clamp load and evens sealing load across the bore.
