You're kinda missing the point here. I'm not trying to talk you into running PRW rockers. What I'm trying to explain, is that all roller rockers need to have the geometry set, because it is not built into the rocker. You may find a rocker that fits on the head with the roller perfectly centered when the valve is on the seat, but that isn't good geometry. Nether is a centered sweep when the sweep is excessively wide. The pic is of a 505 pump gas street build with a .585" lift hydraulic roller and with that rocker, it has .029" sweep across the valve tip. The fact that it is centered, is because I offset the shaft accordingly when I raised the it to minimize the sweep.
FWIW, I avoid rockers that use ball style adjusters. I know that makes me a heretic, but I know the negative effect they have on pushrod side geometry. I'll just have to live with the shame.
