This Cometic MLS head gasket for GM LS small block V8 engines (4.100" bore, .060" compressed thickness) uses multiple embossed stainless steel layers with Viton-coated outer faces for heat-resistant sealing. The uncoated stainless shim layer allows thickness tuning. MLS construction provides rebound, corrosion resistance, and secure sealing between aluminum and iron surfaces without the need for sealants.
