Cometic MLS head gasket for GM LS Gen‑3/4 small block V8 with a 4.060" bore and .051" compressed thickness. It seals modern LS engines without sealants and suits aluminum head/block assemblies. The gasket combines multiple embossed stainless steel layers with Viton‑coated outer faces and an uncoated shim core. This multilayer design rebounds under load, resists corrosion, reduces required clamp load and evens sealing pressure.
