Kibblewhite has researched, tested and chemically separated several cast iron blends, and ultimately specified a combination of ingredients to meet the needs of Harley-Davidson engines. KPM material includes specific amounts of key elements such as carbon, silicon, manganese, nickel, copper and sulfur to create a highly pearlitic structure wit dense fine grains for excellent wear resistance. This "recipe" also allows for a superior surface fnish in the guide bore that is easy on valve stems.

Cannonball Cylinder Heads for Knucklehead
These Knucklehead style cylinder heads are precise reproductions of the stock counterparts and show all the small details like cast-in number tags and foundry markings. Thus they make for great replacements for your worn top end or to build a factory look-alike engine. They are manufactured after 1940-1947 heads with large intake ports. The pre-installed, but unmachined valve seats are sized for stock intake and exhaust valves and hardened for the use of today’s unleaded fuels.
KPM Black Diamond Valves - for Knucklehead 1936-1947
KPM Valve Stem Seal Installation Caps
Plastic caps for a smooth and safe installation of your new valve stem seals. Three sizes available: green=5/16” (all Evos + intake ironhead Sportster), yellow=11/32” (exhaust only ironhead Sportster), red=3/8” (Pans + Shovels).
KPM Black Diamond Valves
Kibblewhite Black Diamond valves are CNC machined from one-piece forgings of EV8 stainless steel. The proprietary Black Diamond multi-stage process treats the shaft to a depth of 0.002” creating a hard, smooth and corrosion resistant surface that cannot flake crack or peel off. The valve tips feature welded-on stellite tips for improved resistance to the impact and abrasive wear of the rocker arms. All versions work with modern lead-free fuels.
