Exhaust Valve

(Inconel / 31.5mm - 1mm Over)

These valves are 1MM larger than stock, great for ported street heads that don't need the huge 2.5mm oversized valves. These Inconel valves are lighter than the stock steel valves and are extremely heat resistant; These are a special high nickel-based alloy that goes through a unique heat-treatment process, which yields extreme heat resistance and enormous tensile strength properties 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.

Features:

• Larger for more airflow
• Made from temperature resistant Inconel
• 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
