Ferrea Honda H22A1/A4 30.5mm 5.48mm 107.1mm 22 Deg Flo +.5mm Super Alloy Exhaust Valve - Set of 8

If you're rebuilding the top end of your Honda H22A1 or H22A4 engine, you'll want to make sure your valves can handle the heat and pressure. These Ferrea Super Alloy exhaust valves are built for that job. They're designed to replace your stock valves and are sized at 30.5mm for the head diameter, with a 5.48mm stem and a length of 107.1mm. The 22-degree seat angle is a common spec that helps ensure a good seal.

What sets these apart is the Super Alloy material. This is a well-built material that's known for its strength and resistance to high temperatures, which is crucial for exhaust valves that see a lot of heat. The fact that these are a +.5mm size means they are slightly larger than stock, which can be beneficial for performance builds or if you're dealing with slightly worn valve seats. This set includes all 8 exhaust valves you'll need for a complete engine rebuild.
