Cometic MLS head gasket for GM LS-series Gen-3/4 small-block V8s (LS1/LS2/LS3/LS6) with a 3.910" bore and 0.027" compressed thickness. Multiple embossed stainless layers with Viton-coated outer faces and an uncoated stainless shim core deliver reliable, sealant-free sealing. MLS construction rebounds and resists corrosion, accommodates aluminum-to-iron interfaces, and evens clamp forces to reduce bore distortion and preserve a consistent head seal under high-output conditions.
