You can put a 4.0 head on a 4.2 it will bolt on you use the 4.0 head gasket and you have to use the 4.0 fuel injection intake and exhaust manifolds the 4.2 ports are not in the same locations, and there is a coolant passage issue between the head and block on some I have read about but I have never run into this issue myself and have put this combo together few times

P.S. If you do this use the stuff from 91 and newer 4.0s the 87-90 stuff is problematic and not worth the effort.
