Pulled my plugs and to me they seem good but wanted opinions. What do you guys think? Any changes I should make?

How many miles on them? Seems to be firing well, good color on the insulator.
 
Is VP 110 leaded gas? Timing seems alright. Not seeing much heat into the threads. Maybe a touch lean..
 
10.50/gal....ouch....Do you have e85 near your? If so, converting to e85 would pay for itself in 1 summer of driving, no joke (a little over $2/gal).
 
You can get an angle grinder with cut off disc. Cut the crimp right above the hex and pull the porcelain right out. Easy to see the WOT part throttle. This is NOT an example of good plug.

Took it to the track and it started missing pretty good so I left off of it. Pulled the plugs again when I got home. They weren't white which was a relief but they were starting to glaze. I changed the plugs and took it out on the road and flat footed it. No miss and actually pulled me into the seat harder then it did at the track. So I'm thinking the plugs fixed it. Before I was running Autolite 3923s and the plug in the pic is the ones I had laying around. They are Autolite 5224s. Still some fine tuning but well see what happens the next go round.

I run cheap autolite 65’s. Cheap so I change them just on a whim.
