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

Since it's always the same bunch that are flowing lots, and always the same bunch that are dribbling., and the new ones were dribbling, and now Sireland67s are dribblers as well , I would have to agree with you that the squirters might be the bad ones. So that means one more test; swapping out the squirters, and swapping in the dribblers, and then in go all the pushrods, and see what comes out the top.
If you still get some rocker arms that seem loose, keep in mind that many of the lifters will be sitting on the base circle, and that if there is less than zero preload on those, then a wobble would just be reflecting that. But again, I'm sure you know that and are keeping an eye out for such an occurance.But per your last post, you've got a good handle on this.
