11mm bolts are all the same, hex head, 11 x 1.5 pitch I believe and about an 
inch or so of threads.  12 mm bolts are threaded all the way.  I think the 
pitch is .25 different than the 11mm bolts.  The washers come with them 
as I recall.  Only one length available.
  There are basically three heads up through the 1.6 engine.  1.5 head which 
has the small bolt holes and small oil return holes.  '81 1.6 engine which 
has large bolt holes and small oil returns.  1.6 head which has large bolt 
holes and large oil return holes.  Oh yeah then there's the hydraulic 
head.  Different oil returns, and oiling to the lifters.
