What material are these exhaust valves made from?

These Manley exhaust valves are constructed from stainless steel. They also feature chrome stems and hard tips for added durability and wear resistance.

Are these valves suitable for high-performance engines?

Yes, these are part of Manley's Race Series, designed for engines operating under 8000 RPM. They are recommended for alcohol engines and feature swirl polished and fully machined surfaces to optimize airflow and combustion efficiency.

What does 'triple groove' refer to on these valves?

About this part

Product Details

If you're rebuilding the top end of a VW 1200-1600 engine, especially for racing applications, these Manley Race Master exhaust valves are a solid option. They're built from stainless steel, which is a good choice for handling the heat and stress inside the combustion chamber. The triple groove design is there to ensure the valve spring retainers stay securely in place, even at higher RPMs.

Manley puts a lot of attention into the details with these valves. They feature chrome stems and hard tips, which helps them hold up better against wear over time. The under-head area is swirl polished to help smooth out airflow, and the combustion face is fully machined to help with efficiency. These are also recommended for use in alcohol-fueled engines, which tend to run hotter and put more stress on exhaust components.

This set includes four exhaust valves, each measuring 35.5mm. They are the 'Race Master' straight stem style, designed for engines operating under 8000 RPM.
