I dont think there is any particular sequence, just tighten them down snug on the head and go back ~ 1-2 weeks after for a final tightening. If you wanna get fancy start tightening from the inside bolts and work your way outward. Someone with a shop manual may have a sequence for you and the specific torque loads. 15-20 ft-lb should be fine (wrist tight).
I have swapped a couple so far on the EP and have no problems.
hth;)
