Do you spray your gaskets before putting them on?

Rather than starting a new thread, I'll just post in this one. I'm just going through all the bolt and plugs on my motor during assembly. I did have new balance shaft bearings put in. Can anyone tell me what these 2 screw in plugs are for. I took the plug out and tapped in there with small screwdriver and it seems like it is the back side of the balance shaft bearing. It doesn't go all the way through. In otherwards, It's a hole that goes nowhere. When the machine shop put the bearing was this hole supposed to line up with a hole on the bearing?
