6.5 ohms? It should be about 2 ohms I would have thought. The ballast resistor is designed to reduce the static current of the coil to about 5 amps (from memory). Most coils I've measured are between 0.5 & 1.2 ohms. I think your problem may be just lack of primary current which is affecting the coil saturation at high revs. Measure your coil's primary resistance and then get a ballast that would give you a static 5A then go from there. If this much current burns your points then change to electonic ignition that triggers from your points.
