5.9 & a solid roller

Rumblefish I think was the OP. I'm fitting a Comp solid roller in a LA 360 (pre magnum) with Lunati Solid roller lifters. The lifters fit no grinding, no problems. Looks like they won't be a problem exposing the dumb bell
section out of the oil gallery/ lifter boss. I'm going to drill the 2,3,4 oil galleries to the crank. And I want to know do people do the oil cross over mod in the valley when running solid rollers? and if yes why?
Cheers
