Cometic's MLS cylinder head gasket for Chevrolet Gen-1 small block V8s (.030 in nominal, 4.030 in bore) is sized for aftermarket heads with undersized water ports to allow customization and fits Brodix 12–23 degree applications. The multi-layer stainless design uses embossed outer layers coated with Viton and an uncoated shim to resist corrosion and rebound under load. It requires no sealants and helps reduce clamp-induced bore distortion.
