Does anyone know if the factory manifold to H-Pipe bolt up uses lock nuts? I have a reproduction set that includes castellated nuts, however they are not crimped to lock on the bolts. Anyone know the correct orientation? It is possible that the castellated side of the nut is placed toward the mounting flange so that the concave surface of the flange wedges the the nut segments tight? My apologies for no photos at the moment.
