Special Notes:
* If you are using late model LT1/LT4 self aligning cylinder heads, you will need to install pushrod guide plates and 7/16 studs for the rockers to work properly.
* If you are using a spring any larger than 1.560 with a 7/16 rocker stud, Harland Sharp recommends our "Heavy Duty" 7/16 series roller rockers.
