Pulled spark plugs out to inspect, I have some questions.

Im running NGK TR-55s. They have roughly 10k miles on them give or take. Im currently waiting on my new headers and I figured I would pull the plugs in the mean time to check them out. Well, on the passenger side, the very back plug was fairly wet with oil. Then on the driver's side, the very back 2 were wet with oil as well. All of them had this whitish color on the tips of them. Anyhow, Im wondering if LS1s are common to have oil on the plugs? How come its only on certain plugs? Is there something wrong with my motor? Why was there oil on the plugs? Lastly, should I clean them up and reinstall them, or buy a new set? Here's some pics, let me know what you think. Thanks.
