Oil cross over or not I need help please.

Hey All. I need help here please. I've been around cars and racing for 46 years - Since I could get a drivers license. This is my first and maybe my last Chrysler unless some thing magical happens! While I like some stuff they have yikes this 360 LA has been a nightmare. I have come over from FoMoCo and after an absence from the drags of a few years I think now maybe I should have listened to others and gone to a cheap belly button SBC . No I had to go down the path least traveled LOL. Parts are non existent in Australia because Chrysler went bust here in the early 1980's and first hand knowledge is limited. This engine is in a slingshot dragster has 4.3 gears a 904 with an 8" turbo action converter. The engine is pretty mild has small dome KB pistons and I'm going to a Comp Cams solid roller. I have Lunati Lifters which seem to fit okay and don't expose the dumb bell section in the middle, so yes I rev it every time it runs. So I have had problems with the rod bearings showing some transfer of material and maybe something that resembles blistering on the cap side while the rod side (upper) bearing shows a bit of oil starvation. Mains looks fine. I have used bi metal bearing for years without incident. The machine work on the crank and rods is sweet and I run .003" clearances. My crankshaft guy has retired so I took my crank and rods at a shop that does a lot of Sprint Car stuff for a fresh set of eyes.
That's the back story. so I have now drilled to 5/16" the galleries 2,3,4 that supply the mains
and have restrictors in the rocker feed gallery to help keep the oil down at the crank. I don't see any advantage with the cross over? What am I missing. As was pointed out earlier I can't block the oil to the drivers side of the lifter gallery because the rocker gear needs that gallery to oil. Help me here before I go crazier!! Also how far up the rear gallery from the oil pump does that plug sit? I have 1 5/8" from the bottom of the block.
Cheers
