GSC Power-Division Super Alloy Exhaust Valves for the 2JZ are for those running high horsepower, high EGT set ups that need a valve that will last in 2000°F conditions. The Super Alloy Exhaust valves have chrome polished stems to create a smooth, durable finish for added life and better lubricity, especially when paired with the GSC Manganese bronze valve guides. Strength, heat resistance, and performance are engineered into every valve. Under head dish is maximized for weight savings while swirl polished and backcut heads promote better air flow without sacrificing durability.

The GSC offering of exhaust valves for the Ford Coyote feature a 45° valve seat contact angle which differs from the OEM 40° design. Due to this change in the design it will require a valve job to be performed to install these valves for proper sealing and valvetrain geometry.
