About This Product
For those looking to improve the breathing of a 74 or 80 cubic inch UL Flathead, these Kibblewhite Black Diamond valves feature an oversized 2.050" head. Like all Black Diamond components, these are one-piece stainless steel forgings with a black nitrided finish for superior durability and reduced friction. This valve is sold individually and fits 1937 to 1948 UL Flathead models. With an overall length of 6.280" and a 0.3715" stem diameter, these valves are engineered for high-performance applications where reliability is still a priority. They represent the best of modern manufacturing for classic American iron, offering precision that exceeds original factory specs.
Manufacturer part number: 20-20743.
