About This Product
These Kibblewhite Black Diamond valves are engineered for the specific needs of the 1937 to 1948 UL Flathead. Each valve is a one-piece stainless steel forging with a black nitrided finish, providing superior resistance to heat, friction, and corrosion. This standard size replacement features a 1.930" head diameter and a 6.280" overall length. Sold individually, these valves are manufactured in the USA using 3-D computer modeling to ensure perfect geometry. They are the ideal choice for the mechanic looking to upgrade a classic Big Twin Flathead with modern materials that maintain the engine's original character while significantly improving longevity.
Manufacturer part number: 20-20742.
