take the worse ones to a machine shop, my triton has cone type seacocks that were pitted and scored. I was able to take a light skim cut off the cone itself, then an adjustment cut at the bottom and they were as good as new.
You don't need to make the adjustment cut on the bottom unless the small end of the cone sits flat on something, there's normally room there.
The unworn and tarnished section directly under the handle shows you the room you have, don't take it all, just enough to clean up the cone.
It's the reason they used a cone instead of a cylender or ball on the old seacocks and other valves, they were designed to be repaired when worn instead of replaced.
Where you see the shadow of the opening doesn't have to be smooth, it contributes nothing to the sealing.
