 The hole that goes from the block to the head for oil supply is like 1/4" or 5/16" in diameter. This is too large, or, maybe one should say overkill. The block has a hole and a little guide dowel right there where the two mate.  By tapping this hole and fitting a plug with a smaller hole, like 1/16" or 1/8" in diameter you reduce the amount of oil going to the head but the amount is still more than enough. Less oil pools up in the cam towers, and, less oil finds its way out of your motor.

This is a common mod for racing and performance engines all over that have "overactive" top end oiling systems. SB Fords, some years/castings, have the issue. My SB Ford for the Lola got plugged because it was far too large as well. Ford FE motors commonly have plugs put in the top end and on some galley areas because they push to much oil in certain places you don't want it, and not enough in other places where you do want it.

Check with Judson, I'm sure he'll help you out on that stuff and other motor questions.
