00º Sioux-Style Nickel Chrome Valve Seat Stones
Goodson valve seat wheels are built to grind accurately and outlast the competition.
We use brass bushing to resist galling or seizing to the holder. Heat-cured, permanent epoxy bonding prevents loose bushings. Our bushings are deep set to expose the most abrasive for long life. Each wheel is pre-trued and checked to assure accurate, vibration-free grinding.
Nickel Chrome Valve Seat Stones are ideal for aluminum heads with chrom-alloy seat inserts. They won't load up or groove. 11/16"x16 thread.
