• Found some have the spot already tapped, with a plug in them. But they are a booger to get off

  most are drilled/plugged..
  
  but they are threaded in metric M10x1.0, witch is VERY CLOSE to 1/8" npt, but not quite the same.

  Very true.  I'm guilty of cranking in a 1/8" pipe thread into one of these holes.  No leaks and never had a problem.  I don't recommend it though.

• For whats its worth, i have been supplying my vnt and the turbo before that with oil from the cylinder head location. I also primed my engine prior to swapping on the vnt and had quite a bit of flow.
