Product Details

The Manley 11665-8 Race Series valve delivers professional-grade performance with over 40 years of engineering excellence behind it. Manufactured from premium stainless steel alloy, this valve is designed to withstand extreme conditions while maximizing airflow in high-performance engines.

Key Features:

  • Premium Race Series stainless steel alloy construction for superior durability
  • Chrome-plated stem for reduced friction and extended valve guide life
  • Swirl-polished underhead surface for improved flow characteristics
  • Fully hardened tip to prevent wear from rocker arm contact
  • Precision-machined combustion face with controlled margin heights
  • Exact stem-to-seat concentricity for optimal sealing and performance
  • Pro-Flo design reduces stem diameter in fillet area for increased airflow and reduced weight

Suitable for applications ranging from street performance builds to 1000+ horsepower race engines, this Manley valve provides the reliability and flow characteristics demanded by serious engine builders. The Race Series construction ensures consistent performance even under severe operating conditions including high boost and elevated temperatures.

Manley valves are compatible with domestic V8 platforms including Chevy LS, Ford Modular, and Chrysler HEMI applications, making them a versatile choice for performance engine builds across multiple platforms.
