Holes drilled in the intake?

I would be more concerned with the dirt dabber dirt in the bolt holes.

the intake would be cleaned up before anything else happens to it. Just trying to figure out what we have here. And, there’s another Chrysler 4 bbl intake that came in the deal with a 400****something prefix that I can’t identify either, my book doesn’t go that high, but I assume it’s after 1974. I was buying a 68 340, he was throwing in parts like these to “sweeten” the deal!
