      A:

      The disk-seat relationship from time to time so the disk will be moved gradually, in increments, through several rotations. During the grinding process, the grinding compound will gradually be displaced from between the seat and disk surfaces; therefore, you must stop every minute or so to replenish the compound. When you do this, wipe both the seat and the disk clean before applying the new compound to the disk face.

      When replacing valves in a head it is nessesary to 'lap' the valve to the valve seat. This insures that the valve will seal the combution chamber properly. Grinding compound is like a liquid sandpaper that you apply to the seating surface. A lapping tool, which is a suction cup on the end of a rod, is stuck on the valve and is rotated back and fourth while applying some downward pressure. The grinding compound needs to be re-applied when you no longer feel it cutting. The compound is wiped off and the seat is inspected. This is a very basic explanation. It's not hard to do but its helpful to ask someone who is familiar with the procedure. Hope this helps.

      to put it in simple terms valves have a seating surface that need to be lapped in. lapping or grinding the valves in help identify any high or low spots. it also shows you where the valve will seat. its very simple to use apply a small amount of the compound to the valve and using the special tool simply lap the valve in. an easy way is to do 120 back in forth motions lifting and turning the valve every 5 strokes. this helps spread the compound out and prevent from gualing. when you are done lapping you should have a ring on both valve seats(almost gray in color)this will ensure you have a proper seat
