What is the main advantage of stainless steel construction for these valves?

Stainless steel offers better resistance to high temperatures compared to standard steel. This improved durability is crucial for exhaust valves that experience extreme heat during engine operation, especially in demanding builds.

Are these valves suitable for a stock engine rebuild?

These are Manley's Race Series valves, designed for engines operating under 8000 RPM and for demanding applications. While they can be used in a stock rebuild, they are particularly beneficial for performance-oriented builds where engine stress is higher.

What does 'Race Master V' refer to in the product name?

The 'Race Master V' designation indicates that this valve features a straight stem design. Manley offers different shapes, and the straight stem is a specific configuration for certain engine builds.

About this part

Product Details

If you're rebuilding the top end of your 1993-2005 Lexus GS300, 2001-2005 Lexus IS300, 1992-2000 Lexus SC300, or 1993-1998 Toyota Supra, especially if you're pushing the engine past 8000 RPM, these Manley Race Series exhaust valves are a solid choice. They're designed to handle the heat and stress that come with demanding engine builds.

Manley builds these valves from stainless steel, which holds up better to high temperatures than stock. The stems are chromed and the tips are hardened to resist wear, giving you more confidence in their longevity. They're also swirl-polished under the head and fully machined on the face to help air move more freely, which can make a difference in how efficiently your engine breathes.

This particular valve is the Race Master style, which means it has a straight stem. Manley recommends these for alcohol-fueled engines, so if you're running that type of fuel, these are a particularly good option for your exhaust side.
