I'm not sure why the diameter of the stud hole is that much bigger than the stud itself (maybe for some heat transfer or expansion so it doesn't crack the block?). But I do know that the hole for each stud just bottoms out. Mine were all filled with some impressive 40 years of gunk.

And of course from all those heat/cooling cycles, I ended up having to weld the nuts onto each stud to get the damn things out!
I ended up cleaning the threads with simple green and a pipe-cleaner type brush. Also used the old stud to chase the threads on a couple, as the ARP studs didn't want to go in easily.
