What is the main benefit of the Race Flo shape?

The Race Flo shape is a specific design choice that works with certain cylinder head porting and valve train configurations. It's intended to optimize airflow for particular racing engine builds.

Are these valves suitable for street use or only racing?

These Race Series valves are meticulously engineered for the rigorous demands of bracket, drag, and oval track racers, especially for engines operating under 8000 RPM. While durable, they are primarily designed for performance applications.

What makes stainless steel a good material for these valves?

Stainless steel construction is used for its durability, especially in high-heat environments. This material choice helps the valves withstand the stresses and temperatures encountered during engine operation.

About this part

Product Details

Starting with a 31.5mm diameter, this Manley Race Flo exhaust valve is built from XH-426 stainless steel, a material chosen for its ability to handle the heat and stress of demanding engine conditions. If you're rebuilding the top end of your 1993-1997 Eagle Talon, especially if you're running a 2.0L 4G63 or 4G63T engine, these valves are a solid choice for improved performance and longevity.

Manley has given these valves a swirl-polished under-head area and a fully machined combustion face. This design helps optimize airflow as exhaust gases exit the cylinder, contributing to better combustion efficiency. The chrome stems and hard tips add another layer of durability, resisting wear and extending the life of the valve train components. These are also recommended for use in alcohol-fueled engines, where exhaust valves face particularly harsh conditions.

This particular valve is the Race Flo shape, designed to work with specific cylinder head porting and valve train setups. Make sure this shape aligns with your engine build plans. For engines operating under 8000 RPM, these valves are engineered to meet the rigorous demands of racing applications.
