The Cometic MLS cylinder head gasket for GM 2.5L Vortec 3000 applications seals a 4.100" bore with a compressed operating thickness of 0.045". Made from multiple embossed stainless steel layers with Viton-coated outer faces, it provides reliable combustion sealing without sealants. The uncoated center shim allows thickness tuning while the multilayer construction rebounds, resists corrosion and evens clamp load to reduce bore distortion for high-output engines.
