One of  the things I want to know is, why did the mechanic grind the valves
at  41,000 miles?  


Charles,
Because they were leaking and needed to be ground?
 
Well the real reason was because some of the early Corvairs used inferior  
valves. Chev made many changes during the early years to correct various  
problems. Bad valves were one, and a poor design that didn't allow the valves 
to  rotate in use was another. The first problem was corrected by using 
stellite  faced valves. Your car apparently was before that change. Valves were 
later  rotated by the four-bead design.
