59A Flathead Engine Standard Bore.

So just pulled off intake manifold to replace sheared generator securing stud. 9/16 UNC.
Noted in the valve gallery some oil present? Correct me please if my thoughts or assumptions are wrong.
There should not normally be oil present here or not. Oil if here will drain back to oil pan via?
This engine has good compressions and good oil presssure. Nil oiling of plugs.
However it uses some oil and noted at acceleration. Reported engine has few miles on rebuild.
Could this oil in this space be taken into combustion space and burnt via inlet valve guides.
The presence of oil in this valve area has me thinking.This area is where the oil is being used as opposed to getting past rings and burning?
Thanks for assistance
