Cometic MLS cylinder head gasket for the GM L18 Vortec 8100 Gen‑VII Big Block V8, .040in compressed thickness with a 4.450in bore for the left side. The gasket's embossed stainless steel layers and Viton-coated outer faces resist corrosion and meet demanding sealing needs. The uncoated shim layer allows thickness tuning while the MLS design distributes load to minimize distortion and perform without additional sealants across mixed-material assemblies.
