Who is Head Boy?

In GoF, it is never mentioned who is Head Boy or, for that matter, 
Head Girl that year.  Is Cedric Head Boy?  It is mentioned that he is 
a prefect, but if he is so wonderful that he is picked as champion, 
wouldnt it be logical that he was also picked as Head Boy?

I think that JKR is somewhat inconsistent about this Head 
Boy/Girl/Prefect thing, only mentioning them when it fits into the 
plot.  However, it seems illogical that we have never been told who 
the other Gryffindor prefects are (other than Percy, and especially 
after he graduates), or who the Head Boy and Girl are.
