Oil cross over or not I need help please.

I'm looking to increase my 360 LA oil volume to the rod bearings by drilling numbers 2,3,4 galleries from the main supply gallery (lifter) to the crank. I have solid roller lifters. Do I need to block the second lifter gallery supply and fit the valley oil cross over or does it need the restriction in the right supply gallery to force the oil back down to the crank. I have had some ordinary looking rod bearings but the mains are fine. I spin up to 7000 rpm
often.
Cheers
