Manley Nissan 3.0L RB30E Exhaust Valve Kit - 35.10mm Head Dia. 124.59mm O/A Length, 0.3136in Stem

If you're rebuilding the top end of your Nissan RB30E engine, getting the right valves is crucial for performance and longevity. These Manley Race Series exhaust valves are built to handle the stress of engines running up to 8000 RPM, making them a solid choice for street or track use.

Constructed from high-quality stainless steel, these exhaust valves are designed to resist the heat and pressure inside your combustion chamber. The stems are chromed for better wear resistance, and the swirl-polished under-head areas along with fully machined combustion faces help optimize airflow into the cylinder. They're also a recommended option for alcohol-fueled engines, which can be particularly demanding on exhaust components.

This kit includes the exhaust valves with a 35.10mm head diameter and a 124.59mm overall length, featuring a 0.3136-inch stem diameter. Make sure to check the manufacturer's instructions for proper installation and any specific requirements for your build.
