I've used the copper tubes, never again. A cross-over just provides a path for oil from the right galley to the left other than the crossover at the front main. If using tubes or bushings, the left galley should be plugged and left dry as lifters are the only thing oiled from that passage. A better choice would be a pressure line to the front of the right galley to bypass the gauntlet of the lifter bores the oil normally has to run through to get to the front of the crank.

A big problem are the 1/4 or 9/32" oil leaks from the main bearing bores to the front four cam bearings. All that oil going up instead of onto the crank needs to be addressed. Other problems are the rear main cap/oil filter mating surface and oil passages matching, oil passages in the back of the block need opened and massaged, and ensure no restrictions on the suction side of the pump.
