Exhaust Valve

(Black Nitride w/ Anti Friction Coating / 30.5mm - 1mm Over)

These valves are 1MM larger than stock, great for ported heads that need more flow through the valves. These Black Nitride valves are lighter than the stock steel valves and have a special anti-friction coating to promote better airflow across the valve as well as reduced resistance in the guide, resulting in better valvetrain stability. These valves will work with the stock seats once a performance valve job has been performed. It is highly recommended to unshroud the valve with a bowl and chamber port work when using oversized valves. Sold individually.

Features:

• Larger for more airflow
• Swirl-polished for max airflow
• Lighter than factory steel valves
• Hardened tips for longer valve life
• May be used with factory valve guides and seals

NOTE: Sold individually.
