The resistors on the 6v ignitions is a ballast resistor, which means it changes resistance as it heats up. It is more a factor of how the system is designed, you can use a "can" coil with a 6v and it does not require a ballast resistor. Ford designed to coil to work at a lower voltage combined with a ballast resistor. This has the advantage of increased voltage at start-up (cold ballast resistor) and then reduced current to the point after warmed up (hot ballast resistor). It is just the design Ford went with.
