Specs At A Glance

Good To Know

Q: Do these require a stud girdle or guide plates? A: Guide plate and girdle needs depend on your cylinder heads and camshaft, so check your head casting and stud hardware before installing.

Q: Can I install these without checking valve geometry? A: Geometry should always be checked with a pushrod length tool, since roller tips change contact patterns and pushrod requirements.

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