Exhaust info needed

I'mm trying to find out if there is much difference between a fireblade exhaust manifold and a blackbird manifold.

does anyone know if the bores are the same or not and if the spacing and fixings are the same.

I reckon I can modify a blade manifold if the only difference is the spacing but not if the bore diameters are different

I would welcome any input.

cheers
