Cometic MLS cylinder head gasket for the GM L18 Vortec 8100 Gen‑VII Big Block V8, .089in compressed thickness with a 4.280in bore for the left side. The gasket stacks embossed stainless steel layers with Viton-coated outer faces to meet demanding sealing environments and resist corrosion. An uncoated stainless shim layer permits thickness variation while the MLS construction reduces clamp load and improves sealing consistency across material interfaces.
