Replacing my points distributor

Good question, or better yet, what about the restoration ballast resistors?
The factory service manual calls for a 0.5-0.6 ohm, and after looking around at the restoration resisters and the limited information I could find was 1.2ohm (mine tested .8-1.0 if I did it correctly). Is that correct for the restoration style resistors?? And my next question is, how does a ballast resistor relate to the coil. The factory calls for a 1.4-1.5 ohm primary resistance coil. aftermarket accel canister style coils are in the .7 primary electronic style or 1.4 point style. How does coil primary relate to ballast resistor primary?

inquiring minds want to know!?????
