These valves are the ultimate combination of materials and have proven themselves in the most radical and extreme diesel engines on the planet. Featuring super strong aerospace grade stainless steel intake valves and super alloy Inconel exhaust valves to take the heat. Everyone is running valve spring pressures that far exceed what the stock valve heads were meant to handle, the added heat from boost just makes them weaker. Good valves now can save your whole engine later. These are drop in for the Yanmar 3TNA72 engines. Can make custom length and diameters upon request. Turnaround time is 2-3 weeks.
Please call us for custom sizes.
