About This Product
These Kibblewhite Black Diamond intake valves are the gold standard for Panhead restorations and performance builds. This standard size replacement valve features a 1.750-inch head diameter and a 0.3765-inch stem diameter, with an overall length of 3.800 inches. It is a direct replacement for OEM 18071-48. Each valve is forged from a single piece of stainless steel and finished with a black nitrided coating for exceptional durability and reduced friction. Designed to fit 1948 through 1965 Panhead models, these USA-made valves are produced using precision CNC equipment to ensure they outperform the original factory components in every measurable way.
