Cometic MLS cylinder head gasket for the GM L18 Vortec 8100 Gen‑VII Big Block V8, .089in compressed thickness with a 4.450in bore for the left side. It uses multiple embossed stainless steel layers and Viton-coated outer layers for heat and chemical resistance. The uncoated center shim can be varied for thickness needs while the MLS architecture helps conform load distribution, lower clamp requirements, and maintain sealing between different head and block materials without sealants.
