Points have worked fine for 100 years.
The only thing that would cause excess current draw through the VR is a shorted field windings in the alternator, a short in the field wire from the VR to the alternator, or an electrical, short behind the VR ir st it's terminals.
Not needed, points work fine, are simple and easily repaired.
Regarding changing to a square back alternator and a 2 field wire electronic VR, again not needed,
I know you spent a bunch on a super dooper aluminum rad and electric fan but if you go back to a copper brass and mechanical fan 1/2 of your issues will be gone.
