I've seen a couple of pics about drilling the lifter bosses, and possibly creating a V notch to catch and direct oil into the drilled holes to increase oil into the cam shaft, and then into the crank. (Picture is taken from an online article at Rods and Customs Mag)

I'm not really as concerned about windage, and loss of hp due to increased drag from oil dripping from the valley into the cam shaft, rods, and then onto the crank. I'd prefer to have a "better" oiled Y Block for a longer life. So, this is my question.

Is it a good practice, when rebuilding a Y to drill holes into the lifter bosses? What Diameter? Should I drill at a perpendicular angle of the lifter4 into the boss (Or straight down towards the crank)? Does it matter? AM I SMOKING CRACK COCAINE?

It is my plan to drill holes in all but the last two lifter bosses, and use about a 1/8 bit. What do the Y Block Gurus think?
