Cometic's MLS head gasket for Chevrolet Gen-1 Small Block V8 is specified with a .140" compressed thickness for 4.100" round bores and 18/23 degree heads. Constructed from multiple embossed stainless steel layers with Viton-coated outer faces, it resists corrosion and rebounds to maintain sealing under varying loads. The design handles aluminum-to-aluminum and aluminum-to-iron pairings without sealants, distributes clamp load and helps control bore distortion.
