One trick I'd thought of to help keep the push rod seated during assembly was to apply grease to push rod end that seats to lifter. Seems I wasn't far off the mark. Applying grease seemed risking in terms of potentially blocking the push rod passage so I tried some engine assembly lube instead. This didn't really help. I'd think if the surface of the lifter was oil free, the grease trick would work. From here: http://web.archive.org/web/20050309065156/http://www.bostonengine.com/articles/waterboxes.html A tip from the Late Great Boston Bob: "PUSH RODS The push rods can hang up on the edge of the lifters which results in no compression. There are some simple tricks to installing push rods. First I have heard that greasing the push rod tip when installing the push rod can help. When I install push rods I push them in, then lift the far end and push again. This is done with the rocker arm installed, using light pressure to hold the rocker in place until you feel the push rods are seated, then install the nuts. A good pen light is very useful to see the down in the push rod."
