Pulled my header off today and looked in the exh ports and # 3 cyl. both valve
stems look wet with oil. Valve seals? All the others are a dry tan color.

Maybe? Could also be blowing past a ring on that cylinder and coating the valve on the way past, but seals would surprise me less. Compression test/leakdown would be a great place to start. Head's probably coming off either way.
If the spark plug is wet or looks like its running rich on the #3 cylinder, rings may be the problem. My guess would be that the valve stem seals are the problem. Good luck
