Flathead Valves

Hi, does anyone know the exact length of a 1934 21 stud flathead valve? Thanks, Bill

For production they probably had at least 10 different, for service it was ground to fit, a new valve was too long

Also you would need a fixture to properly measure it, just measuring total outside length won't work.
