Replaced the dual point with HEI

HEIs do not use ballast. Unlike the stock ignition, they are off when the key is off, so they don't overheat there. And when running, they vary the dwell time to limit current. They simply start the dwell late enough that the current almost never exceeds the module's target. Coils don't instantly go to full current when turned on; it takes time for the current to build.
