Interesting...
I run mine from the pan only as well, and have thought I was lacking by not having it pulling from other passages.
Other set-ups I've seen (like on nascar dry systems [no - am not a nascar fan] - or formula) I've seen where they have 2 of the 4 stages pulling from ea. side of the rear of the head, one pulling from the back of the lifter valley (thru the block - or down thru intake) and one from the pan... but have also seen like yours - pulling from the pan only.
I guess as long as your getting the oil where it needs to be it's all good.
