Yes
79 Darmah
78 900 GTS
86 F1B
80 SSD
02 Harley FXD
72 H2 750 triple
08 KTM 300XC
there has yet to be a motorcycle line made that is as satisfying to ride, hear and look at as the ducati bevels

Can you convert a GT head to SD?

Only if you are very proficient in the use of machine tools.
You have to bore a hole for the closing rocker spindle, very accurately.
Even then, the spacing of the inlet manifold studs would preclude fitting 40mm carbs.
In short, the answer is no, unless you have access to a well equipped workshop.

I bet it wasn't cheap though.
