At least for Nitro it was I believe 54 inches. All the other ones Iv'e seen are also 54 inches (I live out in CA, but have been to Great Adventure, and Batman, Medusa, and the hyper Nitro were all 54 inches). Out here same thing, with Riddlers and Batman.
It depends on the park. I know my home park, SFGAm has a requirement of 54" for the big ones. CP on the other hand has a 52" requirement for MF (to the best of my knowledge. I know B&M's do not have a universal 54", Busch FLA has a 52", and as far as I remember Busch WB has the same... ----------------- Flying High Again.

The height requirements have nothing to do with how tall the ride is or who manufactured it. They have more to do with the forces that riders are subjected to and how the restraints will work on a person of a certain size or height.
I don't think B&M have any coasters of any type with a height requirement other than 54". Here in Florida there are quite a few and all the others I know of are 54" also. Goliath, Titan, MF, Steel Dragon(no one in Japan is 54" tall, LOL), Magnum are all 48" but aren't B&M coasters.
All B&M's I have seen are 54". I think they should look into finding a way to lower those restrictions to 52" or 48". Wouldn't a coaster be more appealing to a park if more people could ride it? Then again, the high requirements keep the line down a little, so I shouldn't be complaining.
