<VV> Bolt Size Question

[Bryan Blackwell]

Hi Bob,

I'm away from DC right now and can't measure, but maybe I can give you  
a useful clue.  The '65 bolts are the same size - not grade, but size  
- as valve cover bolts.  I think they have 7/16" heads, but you can  
check by measuring any standard 1/4" bolt.  The bigger '66 - '69 bolts  
have a special deep, smaller cross section head, which I *think* is  
3/8".
