Manley Performance is known as the leading manufacturer of performance and racing valves. The reason for their success is quality. Manley Race Master SBC series performance valves are a great choice for your bracket, oval track, or high performance street engine. All valves are made from stainless steel 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.

Notes: Use Manley valve lock P/N 13098-16 (7°) or 13153-16 (10°) depending on your spring/retainer choice. Manley stem sizes are .3136” (exh.) and .3133” (int.) respectively. AFR heads have guides sized to .3147” (nominal). Manley strongly recommends that all guides be checked and correctly sized (machine work required) for the Manley valve stem sizes listed to achieve the proper clearances.
