Been redoing a head and found a couple of handy tips when removing and reinstalling the rocker spindles.
Use a slide hammer to remove the spindles. The one that removes the auto-advance unit also fits the tappet spindles.
Either heat the entire head or use local heat from a MAP torch on the bosses to make the spindle slide out easier.
Put the spindles in the freezer before reinstalling.
install the plain washer first with a bit of grease, then rocker arm, then thackery washer on the inside.
Use a 1/2" diameter bolt to get everything aligned.
Either heat the entire head or use spot heat again.
Tap the spindle in with the flats facing out from the center of the head. Front flats facing front of bike, rear flats to rear of bike.
Leave about 1/4 inch of the spindle sticking out, you should still be able to turn it with a screw driver at this point, if not pull it out a little more.
Install the inner tappet cover plate with the ears loosely. I use the studs from the front rocker covers. Line the spindle up so the ears match the slot in the spindle.
Now with a punch on the cover plate drive the spindle the rest of the way home. It should be either flush or slightly recessed. Using the cover plate to drive it home keeps the spindle from rotating out of position.
