Cometic's MLS cylinder head gasket for Chevrolet Gen-1 small block V8s (.036 in nominal, 4.125 in bore) is intended for Brodix 12–23 degree heads and aftermarket configurations. Its multi-layer stainless design uses embossed outer layers coated with Viton and an uncoated center shim to provide corrosion resistance, rebound, and consistent load distribution. The gasket needs no sealants and helps limit bore distortion from clamp load.
