Burnishing in?

[Jalopy Tin]

I have only adjusted the front and rear sides of the cap to get the accurat end play. In my engine the front, main and rear cap has their triangle marking pointing toward the water pump. When i recieved the new cap from the Lang's and i should have the thickest part of babbit pointing toward the crankshaft flange, the triangle marking pointed to the other side.. turned 180 deg. Are MY original main caps turned the wrong side?
In the second picture it looks like the line bore on the new cap is obliqued drilled. What do You think?
When i lay the cap on the crankshaft, it wiggles side to side and when i tighten the nuts as much as i can still turning the crankshaft, i will still have the 1/8" gap on both sides where the shims are supposed to be AND i will get a wear marking inside the cap. (pics three) Btw my crankshaft is 1,248" in diameter and the new cap is 1,249" on one side and 1,251" on the other. Maybe i got an oversized by misstake? I asked if i could use a standard cap for my 1,248" crank and was answered yes.
