<VV> Dropped valve seat in Colorado

[HallGrenn at aol.com]

Randy,
 
That's the first half.   Apparently steel seats in aluminum heads  don't 
like the rapid cool down when you go down the hill after heating up on the  
climb.  So you want to shift up after you crest the hill so you don't  descend 
in a lower gear at first which causes rapid cooling.  Let the heads  cool 
off gradually after the hot climb.

In  Colorado you have good hills.  Do you, when going up them, drop your  
'Vair down into the next lower gear to climb over them?  I read that tip  
somewhere and I can't remember where.  It's supposed to increase the air  flow 
over the cylinders to dissapate the excess heat.  I've followed that  advice 
for nearly 30 years (my 'Vairs are driven daily) and in pulling some  of 
Pennsylvania's best hills haven't lost a valve seat yet.
