How do my plugs look

[ff6849]

This is what my plugs look like after 1000 miles of running over the past 8-10 months, is this what they should like the car runs like a top starts right up, had some pinging issues during the hottest part of the summer (110' welcome to desert southwest) with the A/C running, added a little racing gas and the pinging when away. Back to running 91 octane and no problems. Just trying to fine tune and dial in the car.

Looks OK to me , tan center & not overly black on the top of the threads , How is it running ?

I just finished the car February, its been running great and starts right up, had some minior issues This is my first build so I am a little worried about everything I did most of the work myself with a lot help from friends, and a lot help from board. Just wanted to pull some plugs to make sure everything was working as it should, looks as if it is. So I can start  worrying about some other fictitious problems.

Look a tad rich to me, but maybe put in some new ones to verify, since these supported
a new engine break-in. Rings gotta seal, and all that cam lube, etc.

I'd say they are mis-firing!
