Anytime one can precisely control the fuel supplied to an ICE is an improvement. In this case your ROI may not be worth the effort as the head design will limit a throttle body EFI as it does a carb. Long intake runners with lots of bends into siamesed intake ports, low compression and a low redline combine as some of the limiting factors.
That said you could possibly squeeze out a little more power & MPG and get a more dependable fuel delivery system which may make it worth while to you.
Value is in the eye of the beholder, or something like that.
Good luck
