what are roller rockers ?

[bonnie john]

are they like crane ones for chevy's with a roller tip and a roller rocker shaft or do they just have a roller contacting the top of the valve stem

Roller tip in contact with valve. Some with different ratios than stock. Some with bearings around shaft, most with normal bushings.
