Type of plugs and wires to use on 912E

[HarryDude]

I am using a flame thrower ignition coil and Pertronix Igniter II on a 1976 912E Porsche. do I use resistive or non-resistor spark plugs? BPR6ES or BP6ES?? Also do I increase the gap? if yes to what size? Do I use standard spark-plug wires or solid copper?
