1. Make a light pass with the 45° cutter to remove any possible
burrs at the edges of the seat.
2. After resurfacing the seats, inspection for even valve seating.
3. Apply a light coat of Prussian Blue or erasable felt-tipped
marker ink to the valve faces.
4. Insert the valves, and then lift them and snap them closed
against their seats several times. Be sure the valve does not
rotate on the seat. The seating surfacing, as shown by the
transferred marking compound, should have good contact all
the way around.
Note
To avoid severe engine damage, be sure to remove all
lapping compound from the head before reassembling.
5. Check the valve clearance after reassembly.
