I wonder how the gears were damaged in the first instance. If this occurred by attempting to change speed whilst the lathe was still running then provided you don't repeat this mistake then your repaired gears may last just fine. Only way to tell is to run it I guess. Best option would have been to buy replacement gears if available (and affordable!) making new may not be such a good idea unless you know what steel they're made from and possible heat treatment etc etc. I'd try it with what you have a see how you get on.
