I was thinking about plugging those holes the other day, I figured it'd be easy to find NPT thread with a drill diameter closest to the size of the hole (drill them out slightly larger if necessary). Then just tap them and put pipe plugs, you could also install barbed fittings if you wanted to use them to pull vacuum.
