<VV> engine cooling

    Since it's rather difficult to actually "see" the  position of the 
thermostat doors while driving at normal road speed, I'm  assuming you stopped the 
car, left it idling, jumped out and ran back to find  both doors nearly closed. 
 This is normal since the doors will only fully  open under significant 
engine load and will quickly start to move toward closed  position at idle.
    The only way to tell if the car is running at a  reasonable temp (say 300 
to 400 deg.F. on a stock Corsa or Spyder gauge) is to  install a temp gauge, 
just like water cooled cars usually have.

Is it  possible for a Corvair to run "too cool"? After deflashing the 95HP 
cylinder  heads, using a 12 plate oil cooler with both side shrouds, using the 
Otto  Parts pan and valve covers, both of my rear doors barely start to open 
and  then close again very quickly when driving. I know both doors move freely 
and  both thermostats are operating properly.
Is it dangerous for an Corvair  engine to be operating in low temps (0 
degrees F to 40 F)? I have heard about  starting an engine with cold temps. and 
valve seats coming out of heads.I am  getting ready to take a (long) drive of 
about 600 
miles.Since losing an  intake seat on my 140 PG Rampside I am now nervous.
Thank  you,
