Supertech VW 2.0L 16V 29.50x6.94x98.20mm +1.5mm Oversize Dish Inconel Exhaust Valve - Set of 10

If you're rebuilding the top end of a VW 2.0L 16V engine, especially for performance applications, these Supertech Inconel exhaust valves are a solid choice. This set includes ten valves, each measuring 29.50mm in diameter with a 6.94mm stem and a total length of 98.20mm. They are designed to be 1.5mm oversize, which can be beneficial when machining the valve seats to ensure a perfect seal and optimal performance.

The key feature here is the Inconel material. This is a high-nickel, high-chromium alloy known for its exceptional strength and resistance to extreme heat and corrosion. This makes it ideal for exhaust valves, which are subjected to the hottest gases in the combustion cycle. The dish design on the face of the valve is also a performance-oriented feature that can influence combustion chamber volume and airflow characteristics. These valves are well-built and intended to handle the demands of a performance-tuned engine.

When installing these valves, remember they are 1.5mm oversize. This means the cylinder head's valve seats will need to be machined to match the new valve diameter for a proper fit and seal. Always refer to the manufacturer's installation instructions for specific details regarding machining and installation procedures.
