referring to this measurement when preparing a cylinder head
for sunken valves. |
This measurement
is mainly referring to spring pressures. |
This photo
simply shows valve to valve measuring location when big
camshafts, oversize valves or both are being considered. |

Hard Chrome Plating vs KPMI® Black Diamond® Coating
"First and foremost I must point out that not everyone is qualified to make this comparison, unless they have access to and know how to use Vickers hardness testing equipment, and can take a specimen and view it with a high power microscope and then understand the matrix present. Further they must now how these two process are applied and react to the substrate material they are being used on."
"Hard chrome plating is an adhesive process which means the chrome is “laying on and sticking to” the surface of the substrate material. Hard chrome can trap foreign material within the chrome layer and virtually turn that surface into sandpaper, which also allows the surface to become larger than intended. There is such a thing as nearly perfect chrome, which requires a double cleaning process and the diode to be a tube, which helps to create a clean even-layer of chrome. None the less, chrome can come off and is known to gall and lacks lubricity."
"The KPMI® Black Diamond® coating is a process which impregnates the substrate and develops a 2-tenth layer below and above the surface that is 55-65Rc. What this means is a shell develops underneath and above the surface that is very hard and cannot come off under even the most extreme conditions. Further, there is a second process applied on top of this hard shell that produces a very low coefficient of friction, some very slippery stuff."
"In the world of application,
you would be foolish to consider chrome as a superior valve stem coating when
compared to the KPMI® Black Diamond® Coating."
Cycle X Super Flow Valves

Black Diamond Intake Valve (STD.) All KPMI® Black Diamond™ stainless steel valves are impregnated by a special German process to a depth of .002”, with a surface build up of .0002”. 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. Each valve is designed using Finite Element Analysis software, and profiles are tested on our computerized flow bench. Black Diamond™ Valves are lightweight, strong, one piece forgings with profiles that provide excellent flow characteristics.

Red
Viton Kibblewhite Valve KPMI® Red 100% Viton valve stem seals are designed to have optimum fitment, allow , maximum lift, and to give maximum life. KPMI® Red valve stem seals are resistant to high temperatures, petroleum products and the corrosive gasses that are the by-products of combustion. These seals retain their ability to seal in situations where other materials could harden and allow oil to enter the combustion chamber causing detonation, carbon build up and a loss of power. The Red Ones are truly the racers choice. ENV-VSS $19. 99 |
