GSC Power-Division offers this set of 8 super alloy exhaust valves designed for Ford Mustang 5.0L Coyote Gen 1/2 engines in 2011-2017 models. The 31.75mm standard head diameter ensures direct compatibility with stock heads while providing enhanced heat resistance for turbo or supercharged setups. These valves support higher RPM and boost levels with reliable sealing and flow.

Key Features

  • Inconel 751 Material: Handles extreme exhaust gas temperatures up to 1800°F for longer life in high performance applications
  • Precise Dimensions: 31.75mm (1.250in) head diameter, 110.49mm overall length, 7.97mm stem diameter matches OEM specs perfectly
  • Swirl Polished Head: Reduces valve bounce and improves cooling through better heat dissipation during operation
  • One-Piece Forged Design: Delivers strength to prevent failure under high spring pressures and aggressive cam profiles
  • Set of 8 Exhaust Valves: Complete replacement for V8 Coyote Gen 1/2 improving exhaust flow and engine breathing

Product Notes

  • Special swirl polish on valve head requires matching seat machining for peak heat transfer
  • Inspect valve guides and seats before installation to ensure proper clearance
  • Lightweight construction at 0.65 lbs total keeps rotating mass low for quicker revving

Installation Notes

  • Professional installation recommended.
  • Valve seats must be machined to match swirl pattern for optimal performance.
  • Compatible with stock Coyote Gen 1/2 heads and most aftermarket valvetrain components.
