Cometic MLS head gasket for GM L18 Vortec 8100 Gen-VII big block V8 (.051" compressed thickness) with 4.450" bore (right side) features embossed stainless steel outer layers coated with Viton for heat-resistant sealing. The multilayer assembly rebounds under load and tolerates differing surface finishes. Center shim customization helps meet thickness needs while the MLS design promotes uniform load distribution and lessens clamp load without sealants.
