Need opinions on my spark plugs , rich,lean, or just right? It was running rich and I just put 5 gallons of Cam2 in it and seems to be running great. The plugs were fouled before the Cam2. Previous to Cam2 I ran 93 octane gas.

A light gray/brown electrode is usual for a spark plug that is functioning properly on older high performance engines and your 1969 Z28 plug looks good to me.

Yes... this one looks good. And the best part is it's nice and dry. If the other 7 look like thus one, you're good!! And if that's the case, just check the gap and reinstall.

I Just wrote a Check to a talented Painter & Screen artist.
LoL
I shudder to put abrasive in it and actually use it. LoL
^^ Wiseman's Z28 Plugs look pretty good to me esp when compared to Champions troubleshooting plug reading guide.
