<VV> Valve rotators

[Charles Cromwell]

We installed rotators on every Corvair that came in
for a valve job
 Corvair had a lot of problems with valve burning in
the 61 thru 64. Chevrolet changed the valves to a
sodium cooled valve to cure the problem. I was doing
at least one a day, I did two in one day once.
