Cometic MLS head gasket for GM LS-series Gen-3/4 small-block V8s (LS1/LS2/LS3/LS6) with a 3.910" bore and 0.030" compressed thickness. The gasket stacks embossed stainless layers with Viton-coated outer faces and an uncoated stainless shim center to seal without sealants. The MLS design rebounds under load, resists corrosion, tolerates mixed-material interfaces, and distributes clamp loads to limit bore distortion and maintain a reliable seal.
