308 Kingsborne wires

I just got my hands on a set of Kingsborne spark plug wires for a 308/328. They are copper core and the ends go directly on the plugs. Is anyone using this set up and if so are you running a resistor plug. I'm interested in hearing if there is radio noise if you use resistor plugs. I realize that these wires would be a super conductor but once in a while would like to hear the radio. By the way te set looks great and I'd bet they would work grate for track use. So before I install these I'd like to understand if they are noisey. If so I'll most likely sell them. Thanks in advance
