Hi Lynn, I guess I'm gonna end up being the odd man out and the bad guy on this one. 3-angle seat grinding has been around since forever; it is not a "new thing"; ask any machinist in any town, in any shop. By grinding the seat at different angles, the sealing contact point can be moved either up or down along the valve face seating surface. If the contact point is too either too high or too low on the valve, the valve will burn. This is because with combustion temperatures at about 1200 to 1500 degrees, things are hot in that chamber and the valve has to be cooled by it’s being in perfect contact with the head and in a way as to transfer as much of that heat as possible. Believe me when I tell you that anything less that triple grinding of a valve seat is nothing more than absolute, pure and unabashed "shade tree mechanics". Same old story: there is a right way and there is a wrong way. Once again, just my view and stated as such. Allan
