LA small block,Do you put an oil passage in your head stud?

The answer seems rather obvious to me & it would not be to notch a fastener & create a failure point. Enlarge the current hole in the head by 0.010". The hole is already larger than 0.5" to allow for stud/bolt clearance, but not knowing the actual OD, I used 1/2" [ 0.500"] as a reference. Going from 0.500 to 0.510" creates a gap increase equivalent to a 0.072" hole. Since the starting point is greater than 0.500", the hole size it creates will be considerably larger.
