The timing cover has passages (remember the conical seal) for pressurized lube to the cam end and drive pinion bushings and the oil that drains from those makes a bath for the chain, sprockets and oil pump worm gear. The oil level is controlled by the height of the drain hole. Jim's mod drops the oil level, but yours drains it completely. Doesn't seem like a good idea to me.
