With those 6 Volt systems, running a 4.5 Volt coil, make sure your regulator voltage setting is not set too high.. it's best set at around 7.3 Volts or so... Higher voltage = more current = more heat in that resistor.

My 1941 11d truck had one of the original Ford ceramic resistors and it got very hot , causing loss of voltage at the coil.. I reduced the regulator setting to about 7.3V ( it was up at about 8V ) and the problem was not as bad, although it did continue playing up to a degree and I never really solved it - despite trying a NOS coil and various resistors.

As Lynn said, some people use an adapter, do away with the 4.5 coil system and mount a 6v coil away from the distributor/motor altogether ....
