Black Diamond™ Valves, or White Diamond ® , Stock Head Dia. • Dual Spring Titanium Retainer Spring Kit, Which Allows for 0.440” In. and Ex. Valve Lift These pistons have been designed to incorporate a domed piston deck, resulting in a high compression profile and offsetting any change in volume caused by valve dishes. While maintaining compression through piston shape, we’ve minimized moving mass in our stainless steel valve train conversion by lightening our steel valves. The conversion to Black Diamond™ Stainless Steel Valves offers up to double the life over stock Titanium valves without a loss in performance. Important Note: ‡ = The piston, rings, valves and pin clips in this kit are designed to work together as a system. They are NOT COMPATIBLE with O.E.M. components and should ONLY be used with the components in this KPMI® Top End Service Kit. ENGINE
