Ferrea Subaru FA20 30mm 5.45mm 95.3mm 29 Deg Flo Flat Head +1mm 6000 Series Exhaust Valve - Set of 8

If you're rebuilding the top end of your Subaru FA20 engine, especially if you're looking to improve airflow for better performance, these Ferrea 6000 Series exhaust valves are a solid choice. They are designed specifically for the FA20, meaning they'll fit right in without modification to the valve guides.

These valves feature a 30mm head diameter and a 5.45mm stem, with a +1mm oversize to help increase the flow area into the combustion chamber. The flat head design with a 29-degree seat angle is optimized for efficient gas flow. Ferrea uses their 6000 Series alloy, which is known for its strength and resistance to high temperatures, making these valves well-suited for demanding applications where reliability is key.

This set includes all eight exhaust valves needed for a complete engine build. When installing, ensure your valve seats are properly prepared to match the new valve dimensions for optimal sealing and performance.
