Product Details

The Manley 11631B-8 is a high-performance exhaust valve engineered specifically for Ford 4.6L engines. This precision-manufactured valve features a 37.5mm head diameter and is constructed from premium stainless steel alloy for exceptional durability and heat resistance in demanding applications.

Key Features:

  • 37.5mm exhaust valve head diameter optimized for Ford 4.6L performance
  • Premium stainless steel construction for superior corrosion and heat resistance
  • Black nitrided stem finish (B/L designation) for reduced friction and extended wear life
  • Precision-ground stems and machined faces for optimal sealing
  • OEM replacement or performance upgrade for 4.6L Ford modular engines
  • Designed for high-RPM and high-temperature applications

Manley Performance valves are manufactured to exacting tolerances and are a popular choice among engine builders and performance enthusiasts. The black nitride coating on the valve stem reduces friction, improves wear characteristics, and helps prevent galling during high-performance operation.
