Does this intake manifold need resurfacing?

They are 'poor sand casting' flaws.
The gasket should seal ok unless there is a large depression near an edge.
Resurfacing won't really help as new hole likely will appear due do the poor casting.
You could coat the surface with a light coating of sealer before installation to make you feel you did something about it.
Good luck.
