From my experience searching and getting parts and price lists together for my turbo build, I would say that the parts will run you around 2500, more if you need the carbs to match. I say this because there are only a few different parts that you would need over a FI engine (304-316 cam, titanium retainers, billet rocker arms or some variant for strength, etc...)
Getting the machine work done will vary in price but I have heard prices from 250-600 for the head work and 300-750 for block work. Depends on where you go and how much machining needs to be done.
Having someone put it together should be a little cheaper than the machine work but probably not much.
Add that up and you could possibly be better off buying a MM engine that is assembled with a warranty.
