posts by MX-5 seemed to be very accurate in explaining the differences and what the outcome would be from different types of plugs.

Thanks for the compliment!
Although I've been reading this forum for over a year, I didn't have anything to say until now.
I'm the guy who got the #7440 double platinums to market. I do not use them on any forced induction or NOS setup. Stay with the #440 standard copper plug. The 3032s are single platinum in a colder heat range.
