GUIDE PLATES
05-1000
Engine Pro Guide Plates are manufactured using high strength steel for maximum rigidity, stability and flex resistance.
IMPORTANT: Using a push rod guide plate will not remedy incorrect valve train geometry.
· Black oxide coating
· Proper positioning promotes valve train stability
· A must for high lift / high spring pressure engine environments
