Manley Extreme Duty Valves:
Manley Race Master Valves are designed and engineered to withstand the abuse of the track. Race Master valves are targeted by the bracket, drag, and oval track racers, or even those with modified street engines that are operating at engine speeds below 8,000 rpm. These valves are constructed from XH-426 material for the exhaust and NK-842 for the intake valves, making them the strongest valves in their class.
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.
