[Vwdiesel] 1.6l 11mm vs 12mm heads

[LBaird119 at aol.com]

 First decide which engine block it has.  That'll tell you which 
displacement.
It'll either be a 1.6, (CR) or a 1.5 (CK).  All 1.6 have the larger oil 
return 
hole (front).  12mm bolts won't fit through the holes in a CR's head.  
They can be reamed if necessary.  The reverse works, the holes are just 
a bit sloppy.  The mentioned bushing lets a 1.5 head be used on a 
1.6.
