Need engine information '94 Mercury Sable

I blew head on 3.8 '94 Sable. Recall expired. I understand Ford made changes in 3.8 in '96 then another in '97. I want to get a junkyard engine to put in instead of paying a grand to fix old. My question is...What 3.8 engine with the fixes will bolt right in without modifications?

Will a 3.0L V6 bolt up?
