I'm rebuilding a 1990 EJ22 to plunk back into my 1984 Vanagon.  I've never done this before and am stuck on the valve stems that came in the EJ22 rebuild kit I ordered off an eBay company that has since failed.  There are 8 blue and 8 brown valve stems; however - unless I'm mistaken about where they really go - I only have 4 of 8 exhaust valve ports available because four of them are stuffed with cylindrical dowel pins (two exhaust ports on each head). 
  
Or am I simply mistaken and do the valve stems not go into the cylinder heads below the rocker arms? 
  
If a picture will help, I'll post it tomorrow as I'm tired, cold, and managed to come inside to find a beer needed my company.  Cheers!
