To allow for use as a pressure reference, either boost or vacuum. I, like others, have to use a boost log to send boost pressures to various control systems. With this I wouldn't. If you don't.need them just plug them.

On my LOD intake manifold, which is similar, there were 3 of them. The larger one we used for the brake booster, one for the out tube for my catch can, and plugged the 3rd one as it wasn't used..
