Manley Dodge 8.0L Viper V10 Exhaust Valve Kit - 1.600in Head Dia. 5.97mm O/A Length, 0.3110in Stem

Starting with a 1.600-inch head diameter, these Manley Race Series exhaust valves are built for serious performance in your Dodge 8.0L Viper V10. They're constructed from high-quality stainless steel, specifically the XH-426 alloy for exhaust, which stands up to the heat and stress of high-RPM operation, up to 8000 RPM. This makes them a solid option if you're rebuilding the top end of your V10 and want parts that can handle the load.

Beyond the base material, Manley adds chrome stems and hard tips to these valves, which helps them resist wear and last longer, especially in demanding conditions. The under-head areas are swirl polished to help smooth out airflow, and the combustion faces are fully machined. This attention to detail helps optimize how efficiently your engine breathes and burns fuel. If you're running alcohol in your engine, these are specifically recommended for exhaust valve use, offering reliable performance when you need it most.
