Cometic MLS head gasket for GM L18 Vortec 8100 Gen-VII big block V8 (.140" compressed thickness) with 4.280" bore (right side) combines embossed stainless steel layers and Viton-coated outer layers for high-temperature sealing performance. The multi-layer assembly rebounds under load and resists corrosion across varied surface finishes. Center shim options permit tailored thickness while the MLS design helps minimize bore distortion and avoids the need for sealants.
