It depends on how worn "worn" is. If there is enough material left on the valve sleeve, replating is safe. If they are worn (like my 1911 Holton long cornet) so badly that they cannot be relapped into the casing, a new valve block may be the only "economical" choice. The horn is then no longer "original". It may be cheaper to find another horn..................

My grandfather used spit on the Holton instead of valve oil to keep the valves lubricated. Oil has 2 purposes: to keep the valves easy to move AND to keep the wear down. Spit kept the valves moving but did not do a good job of protecting against wear................
