Just from looking at the pictures there seems to be a lot of "unusual" techniques at work.
The rocker arms appear to be Dove roller tip rockers.
Judging the gauge of spring wire used, the lack of shims in needed positions, along with the lack of spacers as well it does raise questions about the configuration, duh.
Are the lateral springs strong enough to hold their length or are they easy to compress? From what has occurred they don't appear to be doing their job.
There is a respectable amount of lateral pressure exerted during mid-high rpms. Thats why spools are used in a lot of set ups and not just springs.
In your last shot there does not appear to be any spacers or shims mounted on the shaft between the rocker and the shaft stand, which would allow the side wall of the aluminum rocker arm to rub directly against the steel shaft stand.
Its really hard to make an accurate judgment from looking at a few pictures and I don't want to appear anxious to dump on another guys work.
There do appear to be some unexplainable configurations.
See pic of a rocker shaft that uses "spools" or spacers.
