So i just changed my spark plugs and c2 and c4 had oil on the threads. I have no idea when the sparkplugs were changes last i bought the car last summer and this is the first time ive changed them.
I really hope its not rings.
Im thinking that it may be valve seals
but idk
all input is helpful

All may not be lost. It could vary well be the seals that are in the valve cover around each of the spark plug tubes. In this case the oil would be coming from above and leaking down onto the plug and getting on the threads when removing the plugs. You should post a pick of the plugs in question, from the side and tip so I can see if there is any signs of oil burning, rather then just tube seals leaking.

Changes are its the spark plug tube seals leaking down into the plug hole. was there oil around the spark plug or on the coil?

I wouldnt worry, is the car running fine? Hard to see but as long as the tips are dry your ok. You can replace your tube gaskets in the VC, and/or make sure they are seated properly if they look to be in ok condition! I believe after years of the heating/cooling cycle a bit of oil will seep past the seals and collect.

Hmmm, looks a bit dark at the tips, but I cant really see what I want to see in the pics, if that’s dark from just rich fueling, a shadow, or oil contamination. The threads are obviously wet.

Does the car emit light blue smoke at any point? and how is the oil usage?

just took my car out of storage now that the snow is gone. last year it did seem to burn alot of oil, but i just thought it was normal for the engine.
and no blue smoke out of the exhaust

RELAX! Those plugs look normal for being in an S2000. Probably been in there for a while. Just change em.
