I am not sure what this might imply, but if you look up the cylinder head in the parts fiche that most Yamaha parts vendors use, the complete head part # for the 05 is superseded by part # 5JW-1102-10-00, which is the same part # of the head the 06 and 07 models use. This head uses different intake and exhaust valve guides. If you look at the parts fiche for the original 05 head and previous models, it uses the same intake and exhaust valve guides. Could be that Friendly is right.
But I am like you I thought I saw somewhere on the forum they had published a different valve guide for the older model head.
