Just so we're clear...these are 2 completely different designs. You can switch back to points only if you swap the entire distributor, the coil, the resistor, the spark plugs (remember please the HEI plugs will be gapped wider), the condenser, the rotor, the points and the distributor cap. In other words...everything that went with the points system. Unless you use one of the Pertronix modules (which is very likely to leave you stranded and highly agitated somewhere far away at some unpredictable time). If on the other hand you go with the GM made HEI (as Jerry has advised) you'll have a system which is simpler and has shown a high likelihood of not failing. Good luck!
