About the only differences you will find between those engines is that the 4X4 will have a different oil filter mount, which you can swap your other one in by just removing the filter and a couple of bolts. Suggested if you do this spend the couple of bucks for a new gasket set for the filter mount. Very cheap, good insurance against leaks.
The other difference will be the 1995 intake has a lip on it to use the cut O-ring style thermostat gasket, the 1993 probably still uses a paper gasket. Big deal right.
