41-974? I thought the highest part number for AC-Delco spark plugs was 41-962?

And high boost is ?

heat range can depend on a few things, but 7's should work for a good range of applications, and cheap copper is just fine.

No need for iridium, but no harm in doing so either, especially if plug access is difficult for making regular changes.

If it really is a high boost high power application, then you could consider moving to 8's
