Spark Plugs gone bad

Need help please. Just installed Kooks Headers and high flow cats. After 100 miles spark plug gaps are crazy big from 35 to over 65 on most of them. Stock plugs AC DELCO 41-104. Engine is stock just the headers.
2013 ZL1 only 36,000 miles
Thanks for any help

Looks like the electrodes are gone on some of those plugs. Did you have a tune done after installing the headers and cats?

No tune didn't think tune was needed for just headers and cats.

Major change to how the engine breathes with headers. I’m sure others will tell you as well, you need a tune. I’m surprised your not getting a CEL just from the rear O2’s.

If they are genuine plugs, and genuinely only 100 miles....you seriously need the tuning looked at.

Yes sir you sure do. It changes the A/F ratio. How many miles are on the engine?

Any new plugs would be better. The ones in your photo look like they've about 100,000 miles on them.
