Product Details
If you're rebuilding the top end of a Ford 427 engine, especially one with Medium/Hi Riser or Tunnel Port heads, you'll want to consider these Severe Duty? intake valves from Manley Performance. These valves are crafted from NK-844 material, which Manley states offers over four times the ultimate tensile strength of competing intake valve materials at 1000°F. This means they can handle the intense heat and stress found in high-temperature gasoline engines.
Beyond the advanced material, these valves feature chrome stems and hard tips for added durability. The under-head areas are swirl polished to help with airflow, and the combustion faces are fully machined to optimize combustion efficiency. Manley has put these valves through rigorous fatigue testing, showing they can endure significantly more cycles than many competitors, making them a solid option for demanding builds.
This set includes eight intake valves, each with a 2.250-inch dish diameter, ready to be installed in your Ford 427 engine.
