08’ T100 Cylinder Head Onto 05’ T100 Engine??

Hi everyone,

I have a 2005 Bonneville T100 790cc. It’s in need of a new cylinder head, cams etc.
Does anyone know if I could fit a 2008 cylinder head to my 790 engine ???
Apparently there are 3 different types of head for the carb engine and having spoken to a few parts department guys from main dealers they don’t know the different between them and can’t give me an answer. So just wondering if there is anyone in the know on here.
Thanks
