The armatures can take it but the field windings have larger gauge magnet wire and fewer turns. The standard 2-brush 6-volt types were generally only 30 to 35 amps capable. I'm not sure what a 12-volt conversion would be capable of. A person should use field coils that match the regulator that is needed if possible. The regulator controls it so a 1956 or later generator set up could be used to emulate the design characteristics for an older type.
