Description
Manley Extreme Duty Valves
For high exhaust temperature applications, like Top Fuel, Funny Car, BB Chevy Marine, carburetor restricted Circle Track, and Turbocharged engines the best choice is the use of Inconel and XtremeAlloy exhaust valves. Exotic steel is required simply because of the enormous heat imposed on the exhaust valves in these applications. These valves use Manley's XH-430 Alloy which is superior in hot hardness strength over Manley's XH-428 as well as the competition's EV8 materials. These valves feature Chrome Stems, Hard Tips, Swirl Polished Heads and are fully machined.
