Larry,
Don't be hasty and just replace the burnt valve. Chances are that the damage
extends into the seat. You should have the seats checked at you local machine
shop and repaired or replaced. Lapping valves should only be used after
grinding the valves/seats. Your other exhaust valves are probably
questionable.Don't skimp now... or you will be doing this again. By the way,
what did you
have done the first time?
Good Luck...
