Cometic's MLS cylinder head gasket for Chevrolet Gen-1 small block V8s (.051 in nominal, 4.030 in bore) suits aftermarket heads with undersized water ports and Brodix 12–23 degree configurations. The multi-layer stainless assembly features embossed Viton-coated outer layers and an uncoated shim to provide corrosion resistance, rebound, and reliable sealing between dissimilar materials. It requires no sealants and reduces bore distortion from clamp load.
