What is the primary benefit of stainless steel construction for these valves?

Stainless steel construction offers excellent durability and resistance to corrosion, making these valves well-suited for high-performance and demanding engine conditions.

Are these valves suitable for a stock engine rebuild?

These are Manley's Race Series valves, designed for engines operating under 8000 RPM and often used in racing applications. While they can be used in a performance-oriented rebuild, they are not typically considered a standard replacement for a completely stock, mild engine.

What is the difference between Race Master and Race Flo valve shapes?

The Race Master valves feature a straight stem design, while the Race Flo shape offers a different profile. The choice between them often depends on specific cylinder head porting and airflow requirements for your engine build.

About this part

Product Details

If you're rebuilding the top end of your 1993-2005 Lexus GS300, 2001-2005 IS300, 1992-2000 SC300, or 1993-1998 Toyota Supra, especially if you're pushing the engine past 8000 RPM, these Manley Race Master intake valves are a solid option. They're built to handle the stress of racing applications, whether you're on the drag strip or the oval track.

These valves are constructed from stainless steel, which gives them excellent durability. The stems are chromed and the tips are hardened to resist wear, meaning they'll hold up over time. Manley also swirl polishes the areas under the head and fully machines the combustion faces. This design helps optimize airflow into the cylinder and can contribute to better combustion efficiency. You can choose between the Race Master straight stem design or the Race Flo shape, depending on what works best for your specific engine build.

These are specifically intake valves, and they're a popular choice for engines running on alcohol fuels, offering reliable performance when you need it most.
