What material are these exhaust valves made from?

These Manley exhaust valves are constructed from stainless steel, which is known for its durability and resistance to heat. The stems are chrome-plated and the tips are hardened for additional wear resistance.

Are these valves suitable for all types of fuel?

These specific exhaust valves are recommended for alcohol engines. While they are made from durable stainless steel, their optimal performance and longevity are noted for alcohol-based fuels.

What does 'Race Flo' and 'Bead Loc Groove' mean for these valves?

Race Flo refers to the shape and design of the valve head and stem, optimized for improved airflow. The bead lock groove is a feature on the valve stem that helps secure the valve to certain piston designs, preventing it from coming out of the valve guide under extreme conditions.

About this part

Product Details

If you're rebuilding the top end of your 2009 and up Chrysler Hemi 5.7L engine, these Manley Race Flo exhaust valves are a solid option. They're built from stainless steel, which is a strong material that holds up well under the heat and stress of combustion. The stems are chrome-plated and the tips are hardened, adding extra wear resistance where it counts, especially if you're running your engine up to 8000 RPM.

What really sets these apart is the attention to airflow. The under-head areas are swirl polished, and the combustion faces are fully machined. This helps smooth out the path for exhaust gases to exit, making your engine run more efficiently. They're also recommended for alcohol-based fuels, which can run hotter and require more robust components.

This set includes eight exhaust valves, and they feature a bead lock groove, which is important for certain piston designs. They're a well-built choice for anyone looking to get the most out of their Hemi engine, whether for bracket racing, drag racing, or oval track use.
