Cup Style Pushrod Adjuster Screws

I get what your describing, the threaded cup adjusters are available with either oil holes straight through, which is what I think your talking about and would rely on theoretical oil spray/splash or dribble, or using oil-thru pushrods (I do have Howard’s EDM solid lifters that would work with the pushrods although that is not advised obviously with shaft oiling) and there are the adjusters that have a groove that lines up with rockers for the feed. I see it’s not as easy as one might think. Probably just stick with what I have and get the geometry sorted
