I've been looking around and ran across a few notes on lifter valley vent tubes and whether or not they suitable for street engine. If I were running a flat tappet cam I'd not even consider it because of the reformulation of oils, but I've got a factory roller block. It would seem that redirecting the oil flow to the front and back of the block might be helpful in that the oil rings wouldn't have as much oil throw off to deal with, and I don't think with a roller lifter the extra oil would be needed for cam life.
Any opinions?
