Engineered for extreme gasoline engine temperatures, these valves are crafted from exclusive materials (XH-428 for exhaust and NK-844 for intake), offering unmatched tensile strength compared to competitive alloys. In fatigue testing at 40,000 psi and 1400°F, Manley exhaust valves endured 100 million cycles, while competitors failed after just 100,000, proving a 1,000× longer fatigue life. Each valve features chrome stems, hard tips, and swirl-polished underheads with fully machined combustion faces for superior airflow, efficiency, and wear resistance. Built for those who demand race-winning strength and precision, Manley Severe Duty® Valves set the industry standard for performance and endurance.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eProven fatigue strength for extreme performance\u003c\/li\u003e\n\u003cli\u003eChrome stems and hard tips enhance durability\u003c\/li\u003e\n\u003cli\u003eExotic alloys for superior tensile strength, reliability, and longevity\u003c\/li\u003e\n\u003cli\u003eSwirl polishing and machined faces improved airflow\/optimized efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecs\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManley Valve\u003c\/li\u003e\n\u003cli\u003eIntake, Valve-S\/D 2.055,+100\u003c\/li\u003e\n\u003cli\u003eIntake, Valve-S\/D 2.055,+.100\u003c\/li\u003e\n\u003cli\u003eTip Length: 0.290\u003c\/li\u003e\n\u003cli\u003eValve Tip Length: 0.290\u003c\/li\u003e\n\u003cli\u003eValve Length: 5.010\u003c\/li\u003e\n\u003cli\u003eValve Head Shape: 7 Degree Dish\u003c\/li\u003e\n\u003cli\u003eUnderhead Angle: 12.00\u003c\/li\u003e\n\u003cli\u003eUnderhead Radius: 3\/8\u003c\/li\u003e\n\u003cli\u003eValve Series: Severe Duty?
