3.8 Buick Intake Question

[Turbo Zach]

I have this Weiland intake for my Buick 3.8. There are four small pipe thread holes that are in the corners by the intake runners. What are they for? I think it will be more clear when I take the old intake manifold off. I just want to know what I need to plug before I paint it.

Seems like bracket mounts. The front passenger side holes look to be a mounting point for the AC compressor bracket, or at least the older style of bracket. I'd plug em and leave it if the factory intake doesn't have em.
