What is the primary benefit of the stainless steel construction?

The stainless steel construction offers excellent durability and resistance to wear, making these valves a strong choice for engines operating under demanding conditions. This material helps ensure they hold up over time.

Are these valves suitable for a stock engine rebuild?

These Manley Race Series valves are designed for engines operating up to 8000 RPM and are often used in performance builds. While they can be used in a rebuild, they are best suited for applications where improved airflow and durability are key goals.

What is the difference between Race Master and Race Flo valves?

The Race Master valves, like this part number, feature a straight stem. Manley also offers a Race Flo shape, which has a different stem design intended for specific racing engine requirements. You'll want to choose based on your engine's needs.

About this part

Product Details

If you're rebuilding the top end of your 2008-2014 Scion xB, or a compatible Toyota Camry, Solara, or Scion tC with the 2.4L 2AZFE engine, these Manley Race Series exhaust valves are a solid option. They're designed to handle the demands of engines running up to 8000 RPM, making them a good choice for performance builds.

These valves are made from stainless steel, which is a strong material that holds up well over time. The stems are chrome-plated and the tips are hardened for extra wear resistance, which is important for longevity. Manley also swirl polishes the area under the valve head and fully machines the combustion face. This helps improve how air moves through the engine and can contribute to better combustion efficiency.

This particular set is the Race Master style, which features a straight stem. Manley also offers a Race Flo shape if your engine build requires it. These are also recommended for exhaust valves in alcohol-fueled engines, offering reliable performance in those demanding conditions.
