I realize many people are already using SBC rockers, but just for informational purposes I thought I'd post a couple of pics of the Harland Sharp roller rockers on my Gen II 3.1L MPFI engine.
These are 1.5:1 ratio mounted on adjustable ARP 3/8" conversion studs.
Yes, some have been ground down in certain areas just for a little extra clearance. I'm not sure I needed it, but this works. I did have to modify the lower intake manifold in certain spots where the rockers come too close, but nothing that affects strength or the seal area.
