I'm pretty sure Forge dynamically assigns modded block IDs based on worlds, so IDs are not consistent amongst worlds.
Don't quote me on this though
I think you're right... IIRC Dynamic block IDs were introduced in 1.7 while maintaining the static ID setup, then Dynamic IDs were removed in 1.8.
I would have thought that two worlds created with the same roster of mods would have the same assignments, though...
