The engine may have been designed in the 70s but the ignition system and everything else has been updated over time. There is no apparent reason why it should respond better to copper ones, unless they generate a bigger spark etc for some reason. Can you advise me on why you believe it to be so?

In any case, the copper ones are ok. Get 2 or 4 claw copper ones. Then pull them out once every 12-18 months for an inspection, cleanup, and A light sand down of any accumulate crud on the tips, before reinstallation.
