These Extreme Black Severe Application valves by Howards Cams are engineered for high-rpm and high-horsepower applications. They feature a gloss black nitride finish and are perfect for high temperatures (they run cooler, which improves valve life), nitrous, turbo, and supercharger applications. These valves will give naturally aspirated motors a much greater cylinder flow for good horsepower gains. These valves start off as a one-piece forged high-temperature, high-nickel, stainless steel alloy. They're CNC-finished to strict tolerances, making them the choice for the most demanding race classes. Their black nitride
These Extreme Black Severe Application valves by Howards Cams are engineered for high-rpm and high-horsepower applications. They feature a gloss black nitride finish and are perfect for high temperatures (they run cooler, which improves valve life), nitrous, turbo, and supercharger applications. These valves will give naturally aspirated motors a much greater cylinder flow for good horsepower gains. These valves start off as a one-piece forged high-temperature, high-nickel, stainless steel alloy. They're CNC-finished to strict tolerances, making them the choice for the most demanding race classes. Their black nitride micro-hardness is higher than the stainless steel base material. No process can match it for surface hardness! The surface finish is smoother than with chromed stems, having less friction between the stem and the guide. The black nitride reduces power loss due to there being less valve-guide friction. Their nitride finish is not a coating--it's a process whereby it actually becomes part of the steel, making them ideal for the most demanding applications.
