Actually, using points to trigger the HEI modules, which then trigger the coils, reduces the strain on the points since there will be virtually no current flowing through the points. However, note that using a points system to trigger the HEI modules does NOT allow you to use the GM DIS coils; the dwell would be entirely too long for the 0.4 ohm primary winding.

But that's only on the pre-'79 Hondas; the stuff after '79 came with electronic ignition from the factory, and the reluctors in the stock system work perfectly with the HEI modules and DIS coils, producing nearly the perfect dwell throughout the rev range.
