lifter galley crossover tube

." Incidentally I have the original Larry Atherton book here and it says that only #4&3 main bearings are affected. It also claims that the angle the fittings enter the block are critical to how much oil is diverted to the drivers side but does not tell you what the angles are."

Only #3&4 are affected because #1 is now plugged and fed by tbe crossover. and that makes #2 the end of the passage with all the oil it can handle. IMHO
