Valves & Seats -Intake/Exhaust: Description: Valves
WARNING: This page is about a different car, the 2008 Dodge Magnum, 2008 Dodge Charger, and 2008 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
Valves are made of highly heat-resistant steel and are chrome plated to prevent stem scuffing. The intake valve is a one-piece forging, while the exhaust valve has a forged head with a welded stem for lock groove hardness. The four valves (two intake and two exhaust) employ a three-groove lock design to help facilitate valve rotation.
