I opened up all the factory hard corners and tried to improve flow and reduce restrictions in all the galleys that needed to be addressed. I ordered 16 new rocker pivots as used in the 2014 and newer. That's the ones with the smaller oiling holes. On the 2013, one head had pivots with one size holes and the other head had larger holes. Both styles had holes larger than the 2014 model pivots. This will reduce oil flooding the heads and get more oil to the mains and rods. The pivot change should increase oil pressure by at least a small margin. I think the clearing of the restrictions and smoothing the flow will add some extra pressure at the mains as well. I added the extra fasteners in the pump cover and the plate going from the pump to the oil filter. Plus I got a galley plate like Solidsnake11 made. I'm gonna get a Killer B oil pick up, remove the screen and get an oil pickup bell and screen from a traditional 70's style oil pump. My car had 123k miles on it when it died. It does show signs of the cavitation but it is much less severe than that of the pictures in this thread. Actually its barely visible.
I'll definitely add an oil cooler. I haven't decided if it'll be a sandwich plate or if I'll do some other hybrid deal. Whatever it is, it wont be anything that allows the engine coolant to absorb the heat from the oil. If I go the sandwich plate direction, I'll drill the hole in it like was mentioned earlier in the thread to keep the oil cooler from robbing pressure due to the flow loss due to surface friction in the cooler and lines.
Thanks to everyone that contributed to this thread. If anyone has any good oiling improvements other than what is in this thread, I'd say list them. At least there's an audience here to kick them around.

Did you use the same rocker pivot in both heads?
What I saw in the parts diagrams it looks like the 2014 and up is superseded to 13296AA100 for both heads.
2013 has the right head as 13296AA100 and the left head as using 13296AA070.
I was going to order enough to do both heads in AA100, and enough AA070 to do the left head and measure them. They are only 10 bucks each so not a big deal if I have to toss them.
