Cometic MLS head gasket for GM L18 Vortec 8100 Gen-VII big block V8 (.089" compressed thickness) with 4.450" bore (right side) uses embossed stainless steel layers coated in Viton to provide durable sealing for high-output engines. The laminate construction rebounds and resists corrosion across mixed-material head and block pairings. This gasket evens load distribution, minimizes clamp load requirements and does not require sealants.
