Mopar 318 Ignition upgrade

Hi,

I'm planning to upgrade my ignition system (spark plugs, spark plug wires, ignition coil, in future do a HEI conversion) on my Valiant with 318 (came from a 73 roadrunner).

First step is to change wires, plugs and coil.

For coil my local shop has this:
http://www.summitracing.com/int/parts/msd-8202

Only difference is that in this kit: http://www.summitracing.com/int/parts/msd-8203 the ballast resistor is included but this kit isn't in stock (has to be orderd).

Now does this mean that this coil doesn't work with the original resistor (4 pin https://www.jimsautoparts.com/P4529795.jpg) and I have to order the 8203 version?

Also if I plan to make HEI conversion maybe it's reasonable to look for some different coil, because in this page: http://www.designed2drive.com/ it says so:

A canister style coil requires from 1.0 to 1.5 ohms to survive without overheating.
But the MSD has resistance 0.700 ohm.

I have read some of the threads in this forum abuto the HEI but don't have a clear picture of what is a good recapi for this.

Kristjan.
