I run a ballast resistor on some, not on others.

It's not required, but it doesn't hurt.

More importantly, they require a coil with some resistance, like you'd 
use with points.  In particular, there's an MSD Blaster that should NOT 
be used with the Pertronix, unless you add a resistor to the coil.
