DS650 Kibble White Stainless Steel Valves
You must do a valve job to run the Kibblewhite valves. The stock exhaust valves are cut at 30 degree angle, and the head matches that. The Kibblewhite and most other valves are at a 45 degree angle. This alone is a performance gain, 30 degree valve angle is counter productive to making horsepower.
KPMI Black Diamond valves are CNC-machined from one-piece forgings of EV8 stainless steel, impregnated by a special German process to a depth of .002 in. with a surface buildup of .0002 in. This proprietary, multi-stage process reduces friction and provides superior resistance to wear and corrosion over traditional chrome and nickel electrolysis plating processes. These valves go through an oxidizing and polishing process that creates an extremely smooth surface finish that’s easy on valve guides, and there’s nothing to flake off and get trapped between the valve and guide to cause seizure or wear! KPMI Black Diamond valves are designed using Finite Element Analysis software, with profiles tested on KPMI’s computerized flow bench to provide excellent flow characteristics. These strong, reliable, and lightweight valves are your ticket to ultimate valvetrain performance!
