This video shows some Neway (Sykes Pickavant and Sealey make similar ones) valve seat cutters in use on a 1275 mini cylinder head , Quite expensive new but they do last a long time and also can be found relatively cheaply on ebay. For single angle at a time or more recently 3 angle cutter bits have been made although i haven't tried them.
