Yep. Dwayne Porter has mentioned seeing HS failures (more commonly for small-block than big-block, IIRC).

I don't think Joe Average needs needle-bearing fulcrums w/ a pressurized shaft rocker system. Needle bearings are applicable to applications that rely on oil splash / mist for fulcrum lubrication. A plain bearing setup on a pressurized shaft distributes the load better than needle bearings, even if it doesn't look as sophisticated.
