Supertech Toyota Supra B58B30 28.5x5.95x100.1mm Dish Inconel Exhaust Valve - Set of 12

Supertech is known for making well-built valvetrain components, and this set of 12 Inconel exhaust valves for the Toyota Supra B58B30 engine is a prime example. These aren't your everyday valves; they're built to handle the extreme heat and stress found in high-performance applications. If you're rebuilding the top end of your Supra and want components that can stand up to serious use, these valves are a solid option.

The key here is the Inconel material. This is a nickel-chromium-based superalloy that's incredibly resistant to high temperatures and corrosion. Because exhaust valves operate in one of the hottest environments in your engine, using Inconel helps prevent valve distortion, burning, and premature failure. These valves feature a dish design with specific dimensions: 28.5mm head diameter, 5.95mm stem diameter, and a 100.1mm overall length. This precise sizing ensures they fit correctly within the valve guides and seal properly against the valve seat, which is critical for maintaining compression and engine performance.

This set includes all 12 exhaust valves needed for a complete engine rebuild. When installing, pay close attention to the manufacturer's recommended valve seat runout and lash settings to ensure optimal performance and longevity. Using quality valves like these is a significant step in building a reliable, high-output engine.
