Ferrea Infiniti VR30DDTT 29.50mm 5.46mm 97.50mm 25 Deg Taper Flo +1mm Supr Alloy Exh Valve-Set of 12

If you're rebuilding the top end of your Infiniti VR30DDTT engine, especially for performance applications, upgrading your exhaust valves is a critical step. These Ferrea F2412P exhaust valves are designed to handle the increased demands of a performance build, offering improved flow and durability over stock components. They are specifically made for the VR30DDTT engine, ensuring a direct fit when you're putting your engine back together.

Ferrea uses a Super Alloy material for these valves, which is known for its strength and resistance to high temperatures and pressures found in performance engines. The valves feature a +1mm oversized head diameter (29.50mm) and a Taper Flo design with a 25-degree seat angle. This combination helps to improve exhaust gas flow out of the combustion chamber, which can lead to better engine performance. The overall length is 97.50mm and the stem diameter is 5.46mm, matching the requirements for proper installation in the VR30DDTT cylinder head. This set includes 12 valves, enough for a complete engine build.

When installing these valves, ensure your valve guides are properly sized for the +1mm stems and that the valve seats are compatible with the 25-degree taper. It's always recommended to consult your engine builder or a professional mechanic for specific installation procedures and any other components you might need, such as valve springs and retainers, to match the performance capabilities of these upgraded valves.
