I can say in my case this is not correct. When my heads went for cleaning the shop mixed up all the bearing caps.
They are numbered 1 from the front of the cam to 7 rear. On the A bank all the numbers are on the exhaust side but the logos on the top are not all the same way around. Same on the B bank except for number 6 cap which has the number on the inlet side.
The ONLY way to determine which way around the cap goes is to install them and torque each cap and turn the cam by hand, if the cap is the wrong way around the cam can not be turned by hand.

all well and good; but what if the head has been overheated and warped, cam bores will NOT be in alignment, if you surface deck the head FLAT, the bores will still be out of alignment!
a test would be to install head torqued with out follows, and install cam and AT Least be able to turn cam by HAND.
if things seem correct put your own numbers on ,and eliminate old #s
