What are these in the 3.8l Intake

[Thumb]

Tearing down the wife's '99 mustang 3.8l engine due to I hope is just a blown head gasket. She came back from the store and told me that it was hard to start but ran fine on the way home which was about a mile away. Anyway, I got the intake off and was cleaning it up and seen these little holes which I think are in the exhaust and wonder what they're for? I'm clueless whith these newer engines and with newer I mean I use to work on small blocks back in the 60's and early 70's. I posted a pick of what I'm talking about and they are circled in Orange. I also attached a pick of what I seen when I removed the intake...I just hope everything is OK.

Do they move or are they fixed in place? Or is the center an open port?

They seem to be fixed in place and it looks like they are in the water jacket ports if that's what they are.?

EGR passages. Generally: remove, clean, and reinstall.
