Hesston 6550 removing header

 I got a chance to buy a Hesston 6450 or a 6550 he cant remember for sure it has the slant six christler engine in it,was these good machines? I would rather have a New Holland but this a good deal,but how do you remove the header to haul this thing? It is a 14 ft header with the conditioner rolls,can I take the header off and put it on a small 16 ft trailer and haul the rest of it on a 8 ft wide trailer? Nobody around here uses this kind of a machine but this man asked me if I wanted it and it is about a hundred miles from here,just need some advice
