Specs At A Glance

Good To Know

Q: Do I need to check pushrod length with these rockers? A: Yes, a 1.6 ratio roller rocker can change the geometry enough that pushrod length should be verified. Check clearance at the retainer and guide before running the engine.

Q: Will these work with a stock valve cover? A: Roller rocker bodies are often taller than stamped stock rockers, so internal baffle clearance should be checked. Some builds need a taller or modified valve cover.

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