Specs At A Glance

Good To Know

Q: Do these require adjustable guide plates or pushrod length checks? A: Roller rocker conversions often need pushrod length verified and guide plate alignment checked for proper geometry. Measure your setup before final assembly.

Q: Are these direct replacements for stock stamped rockers? A: They fit the same 7/16 inch stud pattern but should be checked for clearance under stock valve covers. Confirm clearance before running the engine.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
