Manley Budget series performance valves are high-quality valves at very affordable prices. All are made from stainless steel (intakes are NK-480; exhausts are XH-422) with chrome stems and hardened valve tips. They're also swirl polished and fully machined. Both the materials used and the heat-treating process are superior to original equipment replacement pieces. These valves are available in stock length and 0.100 in. longer.
