The Cometic MLS head gasket for GM Dart/Brodix Small Block V8 (.027in spec, 4.270in bore, 4.500in bore center) uses multiple embossed stainless-steel layers for strong sealing without additional sealants. Outer layers are Viton-coated for heat and chemical resistance, and the uncoated center shim can vary to meet thickness needs. MLS construction rebounds to resist corrosion and handles the shearing forces between dissimilar head and block materials.
