On a 2226cc, they may well be 13mm.  1/2" is a good substitute - 12.7mm.
 
(For the purist - the best technique uses a parted-off section of a 
 Beargrip 13mm Allen key cemented into a 13mm Langline wrench ...)

Beware of retrieving the old seat seal - it will decompose and readily fall 
into the manifold.  Replacing the seals is useful with some minor fuel mixture 
problems - the 2226cc engine circulates boost air around the injectors.
