Description

1 valve ONLY. The whole set is sold under part number SD-10023

Just one +1mm over-sized exhaust valve. Use with OEM keepers.

Made from one piece, forged Inconel alloy, fully CNC machined, has a hard chrome treatment and a hard tip. Excellent for those looking to rebuild the cylinder head, or replacing bent valves, and wanting a high-power performance engine.

Inconel is an alloy that cope well with very high temperatures, such as the temperatures exhaust valve are subjected to and attain, especially since, unlike intake valves, there is no fuel that goes through them that would be able to cool them down.

Inconel is used for exhaust valves because Inconel alloy is very well suited for high-temperature and high-pressure environments, it is much more stable than stainless steel at high temperatures, as well as being resistant to corrosion and oxidation.

Inconel valves are widely used in dragsters and funny cars. The CNC process eliminates any imperfections from the forging. They undergo a heat-treatment to ensure proper molecular integrity and uniform grain structure throughout the valve. The Hard chrome plating reduces wear and provide optimum anti-friction performance. Excellent for high-performance or racing applications.

Far superior than stock valves.

Made in USA.
