Cometic MLS cylinder head gasket for the GM L18 Vortec 8100 Gen‑VII Big Block V8, .036in compressed thickness with a 4.450in bore for the left side. It stacks embossed stainless steel layers with Viton-coated outer layers to handle harsh sealing environments and resist corrosion. The uncoated center shim can be varied for thickness requirements while the MLS build conforms load distribution and reduces required clamp load without sealants.
