About this part

Product Details

If you're rebuilding a Ford Boss 429 engine, these Manley Race Master intake valves are a solid option. They're built from stainless steel, which gives them good durability for engines that see a lot of use, especially those running alcohol fuels. The stems are chromed and have hard tips, adding to their wear resistance and making them last longer.

Manley put some thought into airflow here too. The under-head areas are swirl polished, and the combustion faces are fully machined. This helps the engine breathe better and can improve how efficiently it burns fuel. You can choose between the Race Master straight stem design or the Race Flo shape, depending on what your specific engine build needs. These are recommended for engines running up to 8000 RPM.
