Bad answer IMO. Find another shop. The tough thing is these are speed density systems. Cam swap is pretty much going to guarantee you're going to need some tuning (at least anything that makes a worthwhile gain). There's some big hp to unlock in these motors w/ a decent sized cam but you're going to HAVE to tune for it.

That or gut the EFI and drop a carb on the thing and tune it in the garage.
