Did you ever do a vacuum test on your engine? One possibility is you have worn valve guides and your engine has been ingesting some oil. Was the exhaust a bit blue/smoky? Probably didn't put on enough miles to know if it was actually using oil.
As previously mentioned, stuck or worn rings could be a culprit as well.
Once you get some springs off you check and see if you can wiggle the valve in the guide, clearance is only a few thou, with exhaust being a couple thou more. Service manual will say exactly, but I think it's .003 and .005. Best to measure them so you know for sure. Good chance you'll find valve stems with wear on one side and valve guides with a bit of an hour glass shape. Ask me how I know! LOL
Keep going! Once you get everything apart, measured, tested and cleaned, you'll know just what needs to be done and then you can start putting it back together, which is the fun part!

Fortunately it appears to (mostly) just be a reflection, as the actual carbon ring is visible on some inspection. Though the overall carbon buildup is still of concern.
