Good question, and one which a careful reading of the Pertronix website neglects to answer directly, shame on them.  However, they do mention in their online PDF catalog that there are two versions of the basic Flamethrower coil, one having 1.5 ohms resistance, the other 3.0 ohms resistance.  You'd have to read the fine print in the catalog to determine the part numbers for each version.

Since a typical ballast resistor has about 1.5 ohms resistance, I surmise the following:
(1) The 1.5 ohm coil is for use in cars with a ballast resistor;
(2) The 3.0 ohm coil is for use in cars without a ballast resistor.

I do caution that this is merely an educated guess on my part, but it is one I'd rely upon if it were my car.  To be absolutely certain, you could contact the company and get them to make some sort of commitment for your particular circumstances.
