I can't speak for any of the coils you mention but the Napa IC-7 is a universal 6v coil that many have used to replace the stock 6v Packard coils in their cars. As far as I can recall there have been no issues reported with the Napa coils.

If the car has been converted to 12v then I have no suggestions other than a 12v coil and ballast resistor would have been needed. Some of the modern 12v coils have internal ballast resistors and can just hook up with the existing wiring while other coils will require an added external resistor such as Packard chose to do in their 55-6 models. If a coil had an internal resistor and there was also an external in the wiring that could cause some issues.
