Cometic's MLS head gasket for Chevrolet Gen-1 Small Block V8 (.040in, 4.100in bore, round bore) features multilayer stainless steel construction with Viton-coated outer layers and a center shim that can be varied for thickness needs. The MLS design resists corrosion, rebounds to maintain seal under high cylinder pressures, and requires no sealants while helping distribute clamp load to reduce bore distortion.
