Product Details

Manley Performance is well-known for making strong internal engine components, and their Race Series valves are a prime example. This particular intake valve, with its Race Flo shape and 1.940-inch head diameter, is built for Chevy small block engines that see a lot of action, especially those running up to 8000 RPM. Whether you're setting up a bracket car, a drag racer, or an oval track machine, these valves are designed to handle the stress.

Constructed from high-quality stainless steel, these valves offer solid durability. The chrome stems and hard tips are there to help them last longer and resist wear, which is crucial when you're pushing your engine hard. The under-head areas are swirl polished and the combustion faces are fully machined.

These are also a recommended choice for alcohol engines, especially for exhaust applications, showing their resilience in demanding fuel environments.
