Cometic MLS cylinder head gasket for the GM L18 Vortec 8100 Gen‑VII Big Block V8, .040in compressed thickness with a 4.280in bore for the left side. It uses multiple embossed stainless steel layers with Viton-coated outer faces to resist corrosion and harsh sealing environments. The uncoated center shim accommodates thickness needs while the MLS construction reduces clamp load and helps distribute sealing load without additional sealants.
