need help with head stud washers
 

Hi, its been a while since I disassembled my cyl head for my 1968 912, I installed new rings and now am putting it back together. Being that the parts were in 3 different boxes im not sure: does a washer belong under each head stud nut or just the top row outside of the rocker box?

All of the head studs get a washer under the special nuts. Washer size: Outside dia. 19mm, Inside dia. 10.5mm, and they are 2mm thick.

Thanks!
