Supertech M/F Duratec 2.3L Inconel Exhaust Valve +1mm Oversize-Set of 8 (6MM stem with tapered tip)

If you're rebuilding the top end of a Duratec 2.3L engine, especially for performance applications or if the original valves are worn, these Supertech Inconel exhaust valves are a solid choice. They are designed to handle the extreme heat and stress found in performance engines, making them a reliable upgrade over stock components.

These particular valves are made from Inconel, a high-nickel alloy known for its exceptional strength and resistance to high temperatures and corrosion. This makes them ideal for exhaust applications where temperatures can soar. They are also +1mm oversize, which can help improve sealing and performance when used with a freshly machined cylinder head. The 6mm stem with a tapered tip is a common size for many performance builds, ensuring good compatibility with various valvetrain setups.

When installing these, remember they are a direct replacement for the stock exhaust valves, but it's always a good idea to consult your engine's service manual for specific installation procedures and clearances. Using these valves can contribute to improved engine reliability and performance under demanding conditions.
