its not those tubes that causes poor oil to the rocker shafts, its the design of the oil passage to the rocker arms, the oil comes up thru the block till it gets to the head, then it makes a 90 degree turn, then runs along between the block and head for about an inch and a half, then makes another 90 degree turn up thru the head to the hollow head bolt that lets oil into the rocker shaft, its that 1 1/2" passage between the head and block that causes the problen, the heat from the block and head and use of non detergent oil that turns the oil to carbon and plugs that passage, there is no way to clean that passage with out pulling the head, i use a small moto grinder to deepen that passage to help relieve the small restritive passage that ford designed
