16V valves not resurfaceable???

[deadbolt@mindspring.com (S. Coleman)]

Completely normal... yes the valves are sodium filled and most machine shops
will still cut them without problem...  Go for the work and do the things
you know to do with that head Ron.  On a side note... I actually do remember
reading that 16v heads are not resurfacable below .010 and the valves were
not "suppose" to be ground.
What do I know about that?  (3angle valve job, valves cut, head cut .070....
