you drill into the main oil galleries then tread and plug the. the heads get full time oiling from the main gallery. the cam bearing doesn't share any oil.
you then turn the bearing so the holes don't line up to the head oiling passages.

I did this, thinking it was a good idea. It turned out bad, I have had to figure ways out to over come the flood of extra oil, which lowered my hot oil pressure at idle. I think I`ve finally got it . The trick was to overcome it w/o pulling the motor apart !! I still have full time oil, but restricted a bunch !
I wont make that mistake again!-----JMO

440`s (I hear are notorious for having cam bearing bores out of alignment from the factory, they supposedly checked and corrected the bad ones, (I heard).
The guy that did my machine work said the same thing, and he fitted the bearings to make up for it, by honing the out of line ones , w/ the cam I was going to run , that I took in to him. I t evidently worked , no problems.
