He had wired top and bottom of coil 1 to top and bottom of cylinder one. What would be the reason this would not work? If the coils is firing two anyway, why would it matter if both coil one went to cylinder one?

To answer your question, it would not matter. However, if one coil fire both plugs in (for example) cylinder #1 and that coil went bad then the cylinder would be completely dead. By using the wasted spark method, losing a coil would not completely kill a cylinder. If, however, the engine had very high compression, having only one plug firing in the cylinder might cause pre-ignition or detonation. So, every method has trade offs. My guess is that using a single coil per cylinder allowed for the use of very short plug wires that would not have to criss cross the engine. If you want to go to the wasted spark method, you should mount all the coils on the shelf like my car and stownsen914's car. That will allow the plug wires to be routed around the engine instead of over it. Just my .02 C. worth!
