What material are these Manley intake valves made from?

These Manley Race Master intake valves are constructed from stainless steel. They also feature chrome stems and hard tips to improve their longevity and resistance to wear.

What is the benefit of the swirl polished and machined faces on these valves?

The swirl polished under-head areas and fully machined combustion faces are designed to optimize airflow into the combustion chamber. This can contribute to improved engine efficiency and performance.

Are these valves suitable for use with alcohol-based fuels?

While Manley recommends these valves for exhaust applications in alcohol engines, this specific set is for intake valves. For intake valves in alcohol engines, it's always best to consult Manley's specific recommendations for your application.
