spark plug tip evaluation

No expert, but I'll be the first and I'd say they certainly all look acceptable, with 3 being the closest to just a wee bit of excess carbon.

That was my thought. 1,4,and 5 look really good. I broke the porcelain on one of them while i was checking. Have to replace it and was considering to do the other 5.

Thanks for the weigh in!

replace all 6 while you're at it.

And may I suggest AC Delco plugs. Not a fan of Champions.

Consider a can of Sea Foam in the gas tank and go for a good run. Then pull a couple of plugs again for a comparison.

I think they all look petty good. If you are going to use any combustion chamber cleaner, Seafoam or anything that is designed to de-carbon the engine, I would put the old plugs back in for just a few miles and let them take the beating. Why abuse a new set? And yes, definitely go with AC Delco no other brand. Gap them and make sure the negative electrode is centered left to right so you get even fire. Many guys will just gap them but not check the side to side. Your plugs will fire better and last longer if you do.
