What does it mean when there is oil in these holes ??

[CruzNlife1]

The exhaust bolt holes as well as the head bolt holes ?? Pulled the head off the N/A at the junkyard and it just occured to me, the head bolts on the exhaust side were covered in thick gunked up oil in the threads and required effort to get out all the way, and all the exhaust bolts had some oil on them. Bad head ? PLEASE TELL ME NO.... Came from a hit car... I made sure to get a head from a wrecked car... Got it from a 1990 automatic convertible, totaled in the front pretty good. the ports had some carbon buildup as well as the pistons had carbon build up, but didnt seem like oil.. Should I be overly worried about this ?? Thanks guys

valve cover is leaking.

Actually, there is an oil galley that runs near the ends of both of those bolts...the bolts actually nearly touch each other. A bit of loctite or thread sealer will fix the problem.
