Cometic MLS-5 head gasket for GM LS-series Gen-3/4 small-block V8s (LS1/LS2/LS3/LS6) with a 3.910" bore and 0.066" compressed thickness. Multiple embossed stainless layers with Viton-coated outer faces and an uncoated stainless shim center provide sealant-free sealing. The MLS construction rebounds, resists corrosion, handles mixed-metal shearing forces, and evens clamp distribution to reduce bore distortion and support consistent sealing in high-output V8 applications.
