spark plugs

the entire right bank look 'cleaner' or at least not as "sooty".
I'm not losing/burning coolant and it runs beautifully which leads me to believe it is firing. All these plugs went in on the same day. They have all been in the engine for the same span of about 25k miles.
There was nothing wrong with the truck that motivated me to change these plugs. Just a maintenance item.

my 2 cents would be the 1,3,5,7 bank looks fine, 2,4,6,8 to lean, maybe if you swapped o2 sensors although mixture should apply to both banks,possibly injectors? you've helped me a number of times,wish I could be more help,let us know what you figure out,try some techron,or cleaning sensor if you don't want to swap them,i just thought if it duplicated same result on opposite side you'd know

Thanks for all your thoughts. Since the truck is running like a champ I'm not inclined to take action at this point. I put 350 miles on it this weekend without incident.
These are the types of clues our trucks leaves us to indicate what is going to happen next. It keeps me in front of potential problems before they become critical.
