So after a bit of a delay, here is where I am at. I took the lifters apart, put them back together. Didnt find anything unusual. Learned not to use nitrile gloves while doing that. Cleaned all of the pushrods again, they were still clean from the first time. Ran the priming tool without the lifters in the bores and saw plenty of oil flood up from the “front” of the lifter oil gallery, which would flood into #7 and #8 exhaust. Reinstalled lifters and primed again and all but one or two filled with oil. Rotated the engine and got oil from the ones that didnt oil before. Reinstalled pushrods and tightened down rocker arms, and primed again. Got oil out of almost every pushrod/rocker down the odd/driver side of the block. The lifters on the passenger side flowed oil but none of it traveled up the pushrods. Rotated the engine and tried again and still no joy on the passenger side. I have oil flow at the lifters but not going up. In the meantime I smoked the Harbor Freight drill, so it’s back to get another one and keep trying. I have to travel this weekend so either tomorrow or late next week.
I am going to put a link to another site where an issue similar to the one you are dealing with is discussed. It includes more specific information and points of view than it is possible for me to include here. https://chevytalk.org/fusionbb/showtopic.php?tid/244699
