Upon  pulling the tin from the subject engine we found the following:
1. right head 3856632 '64 102 hp
2. left  head   3795960  '62-'63 98  hp 


Hi Mike,
Well they are similar but different. The 3856632 is a '64 110 hp head with  a 
combustion chamber of 50.6270cc (per Bob Kirkman's article in the Tech  Guide)
 
The 3795960 head is a 1961 98 hp head (not '62-63) with a 45.9984 cc  
combustion chamber.
 
You can calculate the CR from these figures but I'd say it's around 8.5 to  
9.0 depending which head your are speaking of, using a 145 cid engine.
Regards,
Bob Helt
