HndaTch627 is correct: Not enough valve lash can cause the valves to burn. When the valves get hot, the stems get longer. If there is not enough clearance, the valve will not seat and hot combustion gasses will go around the valve and burn them. Bad idea to try and make power by cheating on the valve lash specs...
