Ballast Resistors
 

I recently bought 2 MSD Blaster 2 coils from Summit and I was going to replace my stock leading and trailing coils with those. I ordered the ones that come with ballast resistors for the points style distributor. Would it be okay to use the resistors even if I have an electronic dizzy? How do I tell if it's the electronic dizzy anyways? It would have ignitors right? Help me out here guys.
