Specs At A Glance

Good To Know

Q: Will these rocker arms work with a stock valve cover? A: Roller rocker arms are often taller than factory stamped units, so check clearances before final assembly. Verify pushrod length and geometry as part of the install.

Q: Do I need to check valve train geometry after installing these? A: Yes, changing rocker ratio or style affects geometry, so check pushrod length and roller tip contact on the valve stem. Confirm the 7/16" stud size matches your cylinder heads before ordering.

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