"Spark" in Plug Wires

I've seen this many times on engines with headers...the heat from the header melts the wire and the spark goes to the path of least resistance, which is the header primary. I just diagnosed a friend of a friend's misfire with the same exact problem on a big block Malibu this past weekend. You've already ordered new wires, but maybe some of those heat sleeves would be a good idea also...

Did you notice the misfire from it?
Years ago I was looking at my engine as it was running one night. I was using a manual choke at that time and the cable was very close to all the wires on the left bank. It was showing a bluish light from the electric field between the cable and the four wires...not a spark jump,but an effect. Moving the cable away from the wires had no effect on the way the engine was running.
