My take on the oiling system crossover tube for the small block

is there a problem with getting full time rocker oiling with a groove in the 2 and 4 cam journal like Crane and others did? and my flat solid lifter 340 has been going since 1995 with no full time oiling (Hughes said he did testing and at speed the cam spinning fast gives like a steady flow) and I blocked oil to the drivers side with a plug in the front driver side passage. no crossover tube, enlarging passages at filter and from cam to mains per old Dick Landy
