There's no special sequence for bolting down the rocker arms ... just make sure the cam lobe is set to TDC. Also, you'll get resistance on 2-3 rocker assemblies, (others will have valves in closed position) be very careful not to strip any bolts (easy to do with an aluminum head) .... screw down each bolt carefully by hand first, then move around to each corner and screw bolts in equally until assembly is flush.
Here's the torque sequence. Make sure you do the two 90 degree angle torques also!
Good Luck
