Digging back into this thread...I had previously crossed my fingers about the press-in studs for the rockers.
Yeah. That didn't pan out.
I ended up pulling the heads back off, and Tommy Goza was kind enough to pull the press-fit studs, cut threads into the heads and installed new ARP threaded rocker studs. After that, I ended up modifying a set of factory pushrod guides to work with the setup and the engine no longer throws rockers or lifts rocker studs! Imagine that!
I have to go back and dig up pictures and get them hosted on photbucket, but here's a pic from awhile ago of the important parts, haha.
