Another vote for AC45S for the extended nose, for better spark distribution in the chamber.
Don't know why anyone would use a resister (R) plug in these old cars?

Because the resistor will increase the spark intensity at lower engine speeds.

It'll also help keep the static out of your AM radio stations that you never listen to anymore.
