Well, I suppose If you don't mind spending lots of dough the grind is the way
to go. But if you,like most, want to save some cash whenever possible simply
re lapping the valves will be more than suffice providing they lap evenly and
the seat surface is in good shape. replace the valve seals and straight edge
the head surface. I'll be honest,Ican't remember the last time I had to
spring for a complete valve job without seeing obvious damage.
