In summary, the Manley Performance 12335-8 S/D 1.600 Exhaust Valves are a high-performance upgrade for any engine requiring increased exhaust flow and durability. Constructed from premium materials, these valves offer superior heat resistance, improved sealing, and enhanced power output. And with their compatibility with 8mm AFR heads, they are an excellent choice for hot rod and racing applications.
