I 6-0'd someone with Hurricane Moltres a while back. It's cool to see someone else using one.
Have you considered using Leech Seed on Ferro? While its defensive stats are excellent, it can't absorb hits like Lugia because of its lack of reliable recovery. Leech Seed somewhat alleviates this problem and lets it nail bulky switch-ins predicting Gyro. I would suggest you cut an entry hazard for it, preferably rocks.
I think your Moltres set is solid. Specs does not seem necessary. I used a scarf set and had no issues with its power. Some quick calcs reveal that it reliably 2HKOs relevant threats such as the Toed, Vaporeon and Ferro. Life Orb could be helpful for cases involving Bronzong (who otherwise has a chance to survive 2 Fire Blasts in rain).
