Manley Race Flo Valves:
Manley Race series performance valves are a great choice for your bracket, oval track, or high performance street engine. All valves are made from stainless steel (intakes are NK-842; exhausts are XH-426) with chrome stems and hardened valve tips. In addition to being made from high-quality materials, Race series valves are swirl polished and fully machined.
Install Note:
Manley strongly recommends that customers check their valve guide size in order to achieve the proper valve stem to guide clearance. Guides may need to be honed when replacing stock factory valves.
