Stupid question about the coil 120-130

On my 1968 122S, someone back in the stone age had replaced the coil with an old Delco "9-volt" coil, plus a ballast resistor mounted to the firewall, typical of 60's points ignition. This coil is a bit suspect with intermittent missing.

If I were to replace this coil with one from a 240/740/940, would I still need the ballast resistor in series with the coil, or can it run without it? I tried it for a bit but the "modern" coil got REALLY warm. I wouldn't suppose that'd be tied to the dwell of the points would it, or is it indicative of an incorrect resistance in the ballast?

Thank you!
