You did not say whether or not you changed the plug wires when you changed the plugs. I assume so, but if not you may want to try swapping the #7 wire with another wire of similar length at both ends and see if the miss goes away or moves to the new cylinder. Visuals can be misleading with plug wires as they can be easily damaged and break down with age. If they are original to the vehicle, I would not hesitate to change them at this time. The "lack" of miss at highway speed, on an 8-cylinder vehicle, is often the fact that it may not be felt when little or no engine load is present. Other than that, the miss could be caused by a leaky valve (most likely exhaust). This would result in low compression of the cylinder, resulting in misfire. A compression check will find this easily. Leaky fuel injector can also cause misfires. If the cylinder gets too much fuel, the spark may fail occasionally, causing a misfire condition. There are other things that can cause misfires, but not in just a single cylinder such as you describe.
You set the gap at 20 sould be 16,a hesitation or occasional miss is not from the points or condensor, its from the craburator,its a power valve or your float getting the hesitation can be the secondary not feeding at wide open throttle, the carburator is faulty, and plus todays fuel is not meant for carburators
did they change the fuel filter??? if so then i would check to see if you have a miss in one of your cylinders this can be chacked as easy as turning your car on and going around the the muffler and listening to see if it makes a funny noise something like a low cough nothing loud just a little cough. if you cant hear anything like that take it in to a mechanic and have then check the pressure in each one of your cylinders
if it is not either one of those that i am not sure either hope it helps
