I want to know whats "prepped for boost" on this, aside from the head studs.
-professionally reworked stock harness with fuse/relay block and 2 wire easy hookup
Possible, but its usually at least 4 power wires...and we need to know what its reworked FOR. Which trans, truck or car ECM and harness?
- unlocked and base tuned ECU included
This almost never is as plug n play as it sounds. IMO I'd rather have a stock ECM and have it tuned per my requirements.
-new pro-comp head studs (needed for boost applications)
There were horror stories about Pro Comp head studs for a while. Not sure if they still have issues, but I will ALWAYS spend the money for ARP.
-new valve seals, spark plugs, MLS Head gaskets
-heads cleaned and valves lapped
Need more info on this. Were there any dimensional changes made to the head surface (milling etc).

I don't see much in that list that really screams "ready for boost". I also tend to think that "freshened" is a buzzword which substantiates very little. It seems like the block hasn't ever been opened, so that could be a 170k engine that blew a headgasket...owner threw some new gaskets and hardware in (since you have to anyway), and now calls it a fresh boost motor.
Unless he only wants $700, or can find a whole bunch more info, I wouldn't be handing over any cash.
