However, it looks like someone had a picture of a Clevite bearing that they drilled another hole in to match the one in the main saddle. Does anyone think this would be a bad option?
That is actually a very common practice with engine builders and racers, so there is nothing to be concerned with. It just needs to be deburred on the front and back sides of the bearing and a steady hand. Its also a common practice to elongate the oil hole in the blocks main saddle to match the bearing slot, similar to port matching an intake or exhaust port gasket to the head or intake.
