Harland Sharp SBC 7/16" Stud Mount Roller Rocker Arms, 1.5 Ratio, for SBC With Offset Intakes (0.150 Offset)

Notes: The pushrod cups have been moved .0150 to the left & right, on the intake rockers, so special guide plates will be needed. In some cases these rockers can cause damage, rather than make horsepower.

Pre 1974 heads must install a straight 7/16 or 3/8 rocker stud in place of the factory bottleneck style. 1974 to 1991 must machine head for guide plates and drill & tap for 7/16 or 3/8 rocker studs.
