The stock electronic ignition is not CDI, though it is often mis-labeled as such. It is important to note because you cannot use CDI coils with that ignition.
The 3-ohm Dyna coils should work just fine with the factory electronic ignition. As Jeff said, you should get rid of the ceramic ballast resistor. To do that you just connect the two wires together that went to the ballast. (That is assuming you are using both Dyna coils, if you use a stock coil, you need to retain the ballast for that coil.)
If you are using new plug wires, and they are suppression core (resistor wire), you don't need resistor plugs or resistor plug caps. Just one of the three items (wires or plugs or caps) should be resistor type, but not more than one. You can run without any resistor type items, but that will make electronic devices act strange. Meters, tachs, timing lights etc., will be affected.
