The  carbs were from a '61 and had aluminum spacers under the carbs. 
The 1960 Corvairs all had a carb icing problem according to Benzinger's  
speech and articles. So i believe that the alum spacer was there to transmit max  
engine heat to the carbs avoid this icing problem. Don't know about the 61's 
but  it could have been a carryover or something the PO did.
 

Howcum  they changed to the insulators instead? Seems like aluminum would 
only  heat the carbs more.
I think that you have answered your own question. The insulators were there  
to limit the amount of heat to the carbs to avoid the percolating and rich  
mixtures caused by hot engines after a shutdown. All 1961-63 Corvair Rochesters  
all had insufficient venting that caused hot restart problems.



The block is a '64 V 110 truck engine has a pipe  type plug next to where the 
car dip stick boss is on the right side of the  engine. It appears to go 
directly into the oil galley for the  lifters. What was this for? An oil pressure 
tap?
 
Sounds like a universal replacement crankcase or maybe just  a fluke.  The 
pipe plug was for the 1960-61 oil pressure sensing point. Some how your case  
was reverting back to this sensing point too.
