It wouldn't be too difficult. You'd need an intake (either aftermarket 4bbl or stock 1bbl), the carb, and the ignition (coil, distributor, ignition module). The exhaust can stay the same.
I don't know if any stock carbureted ignition stuff plugs directly into the wiring harness in the EFI trucks, so you may have to go all aftermarket with that stuff. A DUI ignition would be a great option. They're around $350, only need one wire (power), and have the distributor, coil, and ignition module on one unit.
If you have an automatic, you may have to deal with the computer controls for shifting.
Lastly, be sure it's legal where you live. Many emissions laws prohibit reverting to carb when you have an EFI motor.

Oh. In that case, not much.
About the only two issues are the head is designed for use with the EFI system. It'll work with the carb though.
The second is, the EFI block doesn't have a provision for the mechanical fuel pump. You'll need to get an aftermarket electric fuel pump with low PSI for carburetors.
Ignore the fact that the EFI head has 16 bolt holes vs. the carb head's 13. 3 will simply go unused.

You might find an intake, etc. here:

If you care about waking up the engine at all an Offy C intake and some EFI exhaust manifolds make a huge difference.
