Have mercy... Been working on this for 4 hours now, got the old bearings removed, and have two new bearings installed. #2 bearing is the one that feeds the rocker shafts, and after two attempts, I can't seem to get the holes in the bearing to line up with the holes in the block. One hole is nice, the other is offset enough that the view down the feed tube in the block looks like a football - only about 1/4 of the area of the hole is available to feed oil up to the rocker shaft.

How big of a problem is this? I've heard of folks restricting flow to the rockers in some situations - I doubt that this was one of those situations...

I compared the old bearing to the new, and I'm pretty sure that it's operator error that is keeping the holes from lining up. Maybe the holes weren't lined up that great from the factory, but I had no reason to check that before now.

Sure would be nice if all three holes in the bearing were oblong like the one at the bottom.
