OK... I managed to find out some details on Corvair cylinder head 
chamber volume.   I found a segment of the supplement via some scrounging.


The question was whether an early 80hp engine would drop compression 
by using '64 vintage 110 heads.   It will not.   It will gain a bit 
of compression.   According to the into in the tech guide supplement, 
the 80hp heads have MORE chamber volume than the '64 110hp 
heads.    Therefor:


An 80hp engine using '64 110 heads will NOT suffer lower 
compression.  In fact it's likely to run a bit better over-all.    (I 
already knew this but needed some confirmation specs in writing from 
a reputable resource to satisfy the masses)



tony..

PS:  there's also hardly any difference at all in chamber volume 
between a '62-'63 102 head and a '64 110 head and they look very much 
alike in any event.
