Cometic's MLS head gasket for Chevrolet Gen-1 Small Block V8 comes with a .089" compressed thickness for 4.100" round bores and 18/23 degree heads. Multiple embossed stainless layers, outer faces coated with Viton, provide heat- and corrosion-resistant sealing. MLS construction rebounds under stress and conforms to surface finishes, eliminating the need for sealants and helping to distribute clamp load while minimizing bore distortion between differing head and block materials.
