Cometic's MLS head gasket for Chevrolet Gen‑1 Small Block V8 delivers durable sealing for rebuilt and high‑output engines. It fits a 4.200 in bore and is nominally 0.030 in thick, featuring valve pocketing and steam holes for proper coolant management. The gasket combines embossed stainless steel outer layers coated with Viton and an uncoated shim layer to resist corrosion, accommodate thickness variation, conform load across the sealing area, and require less clamp load to reduce bore distortion.
