I want to upload a new head but when i upload it it says that that head has already been uploaded (my old head) because they have the same name... how do i upload a new head?

you have to talk to Hampa about this.

I believe the general rule about changing heads is that it won't be done, but there is some flexibility.

hmmmm thats a bit annoying.....the actual file in the heads folder of toribash 2.2 is faulty so i should be able to upload the new one anyway

talk to Hampa about it. If it is wrong, it should be possible to update your head.
