The copper core has neglible resisitance, but the Terminals measure + - 5K ohms (and are stamped 5K in the shield)

I still have the original points ignition, so I'm looking for a replacement set without RFI Suppression.
Do I need the RFI Suppression for the original Transistorized Switch Box?

Do racing set of spark plug wires have low resistance Terminals?
Anyone have a suggestion? Moroso? Accel?
