Lubricate the valve guides with clean engine oil, and apply
oil or water based lapping compound to the face of the
valve.  

NOTE:  Lapping is not required with an interference
angle valve job.

lapping tool or a section of fuel line connected to the valve
stem.

times until the valve is fully seated, and repeat process for
the other valve(s).
