Cometic's MLS head gasket for Chevrolet Gen‑1 Small Block V8 supplies reliable sealing for high‑output rebuilds. It fits a 4.200 in bore and has a nominal 0.092 in thickness, featuring valve pocketing and steam holes for common head designs. The gasket combines embossed stainless steel outer layers coated with Viton and an uncoated shim layer to resist corrosion, permit center‑layer thickness variation, conform sealing load across the surface, and lower clamp load to reduce bore distortion.
