GSC P-D Ford Mustang 5.0L Coyote Gen 1/2 2011-2017 32.75mm Head (+1mm) Super Alloy Exhaust Valve - Set of 8
These GSC Power-Division exhaust valves fit 2011-2017 Ford Mustang GT 5.0L Coyote engines Gen 1 and 2. The set of 8 features a 32.75mm head diameter and +1mm extended length for compatibility with high-lift camshafts. They deliver reliable exhaust flow under high boost and RPM conditions.
Key Features
- Super Alloy Material: Forged Inconel X-750 construction resists extreme exhaust temperatures over 1600°F and provides fatigue resistance for turbo or supercharged setups
- +1mm Extended Length: 106.95mm overall length prevents coil bind with cams over 12.5mm lift while maintaining stock geometry
- 32.75mm Head Diameter: Matches Coyote exhaust ports for increased flow volume without shrouding the valve
- 7.00mm Stem Diameter: OEM-spec size ensures drop-in fit with factory guides and seals
- Swirl Polished and Stellite Tipped: Enhances flow velocity and protects seating surface against wear during high-mileage track use
Product Notes
- One-piece forged design eliminates stem-to-head failure common in multi-piece valves
- Inspect valve springs and retainers for compatibility with +1mm length during install
- Set ships in protective foam-lined box to prevent damage
Installation Notes
- Professional installation recommended.
- Valve seats must be cut to 45° x 1.25mm margin for proper sealing
- Compatible with OEM or aftermarket dual valve springs rated for 12.5mm+ lift
