Really tough to beat a Shimano 600 headset for a 1" threaded application. I have these headsets on all of my threaded fork bicycles. They are smooth, light, and bulletproof. I have one on my son's 1995 Cannondale R900 and it's smooth as butter after 26 years, about 20k miles and two clean and re-grease cycles. You can find clean used ones on eBay for $50 or less.
