Goodson Black Diamond Hyper-Finish Diamond Sizing Kit | BHF-KIT

The NEW Black Diamond Hyper-Finish Diamond Valve Guide sizing System is better than ever

The original Hyper-Finish valve guide honing system was manufactured entirely by hand, which led to variations in quality, sizing and availability. The new system is being manufactured entirely by CNC machine, so human error has been eliminated ensuring consistent sizing and availability.
