If you are getting power to the dizzy and coil, and it is correct....meaning somehow the power simply is not traveling to the plug, then I would verify the rotor and cap are correct for the application, and eliminate that rotating "switch" of power. as the cause. I would also verify the timing of the rotor related to the cap, or the trigger to the rotor. Anything that would make power move, but not at the correct point in time and hence not making it to the plugs. You may even verify the the rotor turns when the starter is keyed(making sure the cam and dizzy gears are doing their thing). Easy enough to make sure the engine ground to frame is good while you are there as well. I doubt all 8 plugs and/or wires are bad.
You are getting there, just step back and pause and don't get frustrated.
