I have done work on a Harley and I had to turn the motor over to top dead center on each cylinder... not entirely sure and DO NOT wanna blow up my new head.
When you remove the valve cover to start the head removal you will see the tops of the push rods with the rockers on top then pivot assemblies and last but not least the bridge that holds them in place using to bolts.
KEEP THEM IN THE EXACT ORDER YOU REMOVE THEM.
Installation is the reverse procedure. Tighten them down ONE TURN AT A TIME until you hit the torque value of 21 ft lbs. No engine rotation is needed.
I would use engine assembly lube of some sort and coat all the friction points during assembly.
I'll post a picture in a minute.
