This “Black Diamond™” process improves wear properties, reduces friction, and provides resistance to corrosion and wear that is superior to chrome and nickel electrolysis plating. Black Diamond™ Valves are light, strong, one-piece forgings with profiles that provide excellent flow characteristics. White Diamond® Valves: We fully CNC machine our White Diamond® Valves from a one-piece forging of either EV8 Stainless Steel or Inconel -751. These materials have proven heat and corrosion resistance properties. A 360-degree anode is used to produce the highest possible grade of hard chrome finish. White Diamond® Valves are light, strong, one-piece forgings with profiles that provide excellent flow characteristics. KPMI® O.E.M. Replacement Tensilite® Titanium Valves • KPMI® Recommended OEM Replacement Valves • Exceeds OEM Specifications • Your OEM Alternative • Compatible with O.E.M. Spring Kits KPMI® Valve Springs: KPMI® valve springs are wound from Premium Kobe Super-Clean Chrome Silicon Wire. KPMI® valve springs are heat-treated, stress relieved, and shot peened to insure maximum performance and life.Springs are engineered for each specific application using proprietary advanced spring design simulation, and analysis software. Engineers pay special attention to cam and spring harmonics, stress, mass, and operating rpm. Application Year Valve Valve Qty. Req.

To meet this need KPMI® has new product line selected from existing or newly developed KPMI® valves for select applications. If you look closely at the KPMI® Tensilite® titanium valves, you will notice the U.S. milled one piece forged design, precision ground stems and the CrN PVD coating covering the entire valve. In cases where the OEM uses steel exhaust valves, KPMI® has elected to implement our race proven line of Black Diamond™ stainless steel exhaust valves, rather than create a new line of valves made from a lesser quality material to match the OEM. For your next factory rebuild, upgrade to KPMI® and gain yourself some performance and reliability, while saving yourself some money. Note: These valves are intended as O.E.M. replacement valves and are completely compatible with the O.E.M. spring kits. However, experienced engine builders, who are running aggressive camshafts or higher than factory RPM’s may find the combination of the O.E.M. Style Valve and KPMI’s Lightweight Racing Spring Kits advisable. † Must use KPMI® Spring Kit when using Black Diamond™ or White Diamond Valves. ## Important note / cylinder head modification required: these KPMI’s Black Diamond™ studs feature a 12mm diameter for the entire stud, providing maximum clamping force for extreme duty and peace of mind. A simple drilling operation with a 1/2” drill bit is required to modify the cylinder head. ENGINE
