Analyze my plugs photos (hot, cold, just right?) please

Hey folks, please analyze my plugs/mixture.

The plugs are (L-R) #1,3,5,7 in my 340 6 Pak engine. (Notice the color change on the electrode tip).

Thanks!

Looking at the pics, I'd say your A/F mixture is near perfect. A light tan is indicative of a well tuned engine.

Agree with Kidd. The reason your end plugs are a bit different from the center ones is the shorter intake runner length, that's all.

You're good to go!
