'89 roller-cam LA 360 w/Magnum heads - new roller lifters not pumping up

When I asked about, is the oil getting out of the lifter elsewhere, I was thinking out the bottom and drizzling all over the roller-wheel or camshaft.I was thinking more along the lines that the bottom of the lifter bores were damaged, but since it doesn't matter where you put them, and now we see that pretty much any new lifter does the same, that rules this idea out. And by now you have probably ruled out oversize lifter-bores.But the one sure thing in all this is that many of them are putting out a lot of oil. Maybe they are the faulty ones. I've never had a roller cam engine open, so I'm no help at all.
