Cometic MLS head gasket for GM L18 Vortec 8100 Gen-VII big block V8 (.045" compressed thickness) with 4.280" bore (right side) features multiple embossed stainless steel layers with Viton-coated outer faces. The multilayer construction rebounds under load and resists corrosion while eliminating the need for sealants. Viton coating tolerates high heat and the center shim layer allows thickness variation for consistent load distribution and reduced bore distortion.
