The Cometic MLS cylinder head gasket for GM LS Gen‑III/IV small block V8 (4.080" bore, .040") uses embossed outer layers and an uncoated stainless shim to improve clamp load and sealability around open-deck blocks. Its HP shim technology evens load distribution, requires less clamp load to reduce bore distortion, and the outer layers are coated for enhanced sealing in demanding conditions.
