Turn the crank until both valves are closed (there's a pattern to make it simple - only moving the crank two or three times, but I don't remember what it is. So, you'll have to turn the crank six times. Remove the spark plugs...)

Torque the pivot screws to 19-21 pound-feet.

Turn the crank to put the next cylinder at firing position.

Repeat for six cylinders.

Before you put the valve cover on, it's not a bad idea to pour a little bit of clean oil into the "bowl" of the rocker arm to help prelube the pivot (I'll put engine assembly lube on the pivots as I put them in, but the extra bit of oiling will also help. Dry starts are a Bad Thing(tm) and should be avoided.)
