Oil on spark plug threads

I have a 76 Cordoba 400 with 4 barrel. This car is all original except for the carb and is like new. The mileage is a pampered 53K. Lots of idle time instead of drive time due to storage
Last week I did my yearly undercarriage inspection and wipe down and noticed 2 oil leaks down the side of the block. Traced to the second cylinder (drivers side) spark plug. I pulled the plug, and it was loose to start, and oil is on the threads and on the perimeter but not on the electrode.
I cannot see any area above like the valve cover leaking - I will inspect closer this weekend.
The only thing that would make sense is possible carbon around the ring. I cannot see bad rings or valve seals with this engine. By the way it does not misfire.
Any ideas or comments would be appreciated. THANX

Big blocks of this aira had a problem of cooking the valve cover gasket, exhaust manafold is close so there is more heat than normal.

I will check that out. I have changed the gaskets out some time ago but makes sense. THANX
