Which of the following statements is not true? Normally the desired valve face-to-seat contact area for intake valves is 1 inch. Normally the desired valve face-to-seat contact area for exhaust valves is 1 inch. The average valve seat width is 0.060 inch and the average seat begins 0.030 inch from the valve margin. A properly reconditioned seat has the correct seat width and sealing position on the valve face.
