The holes are probably a modification (a trick) to the carburetor to aid in getting the engine to idle better with a "wild camshaft". (It's in most of the Holley modification books).
I don't want to say that they are definately there for that reason. They may be there for that reason.
Someone might call me a know it all again if I did.
