A used engine is always a crap shoot.
If possible find one you can hear running, if not just do the long block swap and redo the timing chains, even if it's '03 or newer.
Sensors and other wiring connections and connectors can be moved around and changed from year to year, since 95% of these engine connections are on the intake manifold it is just better to swap your current intake to the new engine so all the wire lengths and connector types will match up
