Copper leads, unsuppressed caps and resistive plugs. Best solution for long term use, IMHO.

Still using the original leads on my 1970 saloon with no problems !!!!!

In case you didn't know, the idea is to have a little resistance in the flow to help the spark build up before it goes pop (simplistic explanation) so you want 5000 ohms, approx, in the system. Carbon leads are about 5000 per foot, copper leads have zero, so, you need either a suppressed cap (5000 ohms is normal/average) or plugs with 5000 in them. NGK plugs have an R in them if they are 'resistive' so a BPR5ES is the resistive version of the BP5ES. I use BPR6ES in the Alta with copper leads and simple caps. If I used the nice NGK reistive caps I'd need to g for BP6ES.
Hope this helps.
