<VV> Cylinder head drawings

[BobHelt at aol.com]

Corsa/CPF recently digitized and posted several cylinder head drawings. Two  
in particular are 1965 95 hp heads, #3856743 and #3883862.
 
 
I have reviewed these two drawings and have not been able to identify any  
differences between them. Has anyone else been reviewing these drawings? Have  
you discovered any differences between these two heads?  Bob Kirkman's Tech  
Guide Sup. article doesn't show any differences either and he was the  "expert".
 
There must be a reason why Chevrolet would release two sets of drawings for  
these heads that appear to be identical. There must be some subtile  
differences.
 
What am I missing?
 
Thanks in advance,
Regards,
Bob Helt
