The Cometic MLS head gasket for Chevrolet Gen-1 Small Block V8 (4.100in bore) with a compressed operating thickness of 0.027in is a multi-layer stainless steel gasket engineered for tight sealing. Its embossed outer layers are coated with Viton for temperature-resistant sealing; an uncoated stainless shim layer allows thickness variation. The MLS design performs between aluminum and cast-iron components without sealants and helps reduce bore distortion through improved load distribution.
