5/8” drive spark plugs on LA heads

OP Here.
Great.
It looked good to me, but I may have overlooked something.
This turned into a brand and heat range thread.
- brings me to……,
Thinkin,…
Iron heads should usually run colder plugs with increased compression.
Aluminum, .. not so much.
Exotic metal plugs are good for longevity. And old copper cores are better for making fire.

but, does anyone have an opinion on the E3s?
