Cometic MLS cylinder head gasket for GM LS Gen-3/4 small block V8s (4.100in bore, .040" thickness) uses multiple embossed stainless-steel layers with Viton-coated outer faces to resist corrosion and handle demanding sealing environments. The multi-layer design reduces required clamp load, helps distribute sealing forces and accommodates surface variations, while embossed outer layers and AMP coatings improve longevity and sealing under high-load conditions.
