LOL, but the way I do them is exactly like you describe, 3 step sequence with whatever final ARP asks for. Just make sure you lube the threads, under the bolt heads and both sides of the washer.
ARP does not give a torque spec. so I'm guessing they defer to the manual. Never had aluminum heads on any of my classics... always rebuilt the cast parts in the past. Unless I hear otherwise I'm going with 95ftlbs. And yup... lube threads and both sides of washers. Galling up these new heads would be a shame.
