Mopar ( Tube Kit ) info requested !

What was the point of tubing the block on one side if you wanted oil to the lifters. Makes no sense. If you wanted to restrict the flow to the lifters, that would make sense, but with a crossover tube you would need to tube both sides.
Please follow xplain.

My “theory” for tubing the main galley but not the other has two reasons. This engine will either get SFT or solid rollers, so maximum flow to the lifters is not necessary- just want a bit to lube the bores. As I mentioned I don’t trust splash oiling alone on a street engine that will see a lot of idling / low rpms. I blocked the oil from leaving the #1 main to the driver side galley so to introduce a little oil to those lifter bores, I ran the crossover.
Second reason for not tubing the driver side galley is that I would just have to drill holes in it to lubricate those lifters. I’m hoping the small diameter line acts as a restricter and won’t flood the driver side oil and cause the usual gushing leaks around each lifter.
So basically I tried to restrict the amount of oil leaking rather than completely plug it off. If I find that the crossover is passing too much oil I will try a smaller line, or possibly a set screws with hole in it, or just remove it and plug the hole. Saves me from the hassle of tubing the other galley. Like I said, it made me nervous doing the first one. I had nightmares of the rearmost lifter bore splitting like a melon as I drove the peener down through.
Clear as mud, right?
