Odd holes drilled in edlbrock aluminum intake

A friend gave me an edlbrock intake manifold a while back, I was looking at it today and noticed two holes drilled in it, one about 3/8” and the other about 1/4”. I can see them looking down through the carb mount. They don’t look factory as one has slag on the edge from drilling. Any idea why someone would drill these holes? I’ll take a pic tomorrow when I go to my shop.
