Help reading spark plugs

i am running the hughes stage 2 (firstgen) 360 heads w/2.02 intakes and 1.62 w 58cc chambers pistons have positive deck height which nets roughly 10.5 ~10.7 @ 4800ft elevation, where I originally built the engine.

Now I am in Dallas sea-level basically, it will not run on 93 pump gas without excessive detonation, so i blend the 114 5 gals per tank.

It looked lean to me as well, but it does have a pretty good burn pattern, and the heatline on the ground electrode is good as well.

I am going to order the strip kit for this tomorrow.
