I'd leave the governor gear in. If you want to replace it, that's a good idea.... but it kind of needs it.
You should replace:
Piston (and rings)
Connecting rod
Valves
Bore it
Grind the crank
Grind the valve seats
Bead blast and plane the head
And obviously, all gaskets and seals
Replace as needed:
Valve guides
Check the camshaft
Rework the lifters and adjuster bolts as necessary
Governor gear
Governor control rod bushing
Check the arm on the governor control rod. Weld it if needed.
Remove the balance gears and chuck them in the scrap.
