the swap you describe does not require an intake swap.
so pull the one and swap in the other.
however, if your car has an auto transmission, it is WAY easier to remove the flex plate bolts if the intake manifold has been removed.
so i pull the intake,
remove the flex plate bolts,
reposition the intake with several bolts to hold it,
and then lift the engine.
the install is the reverse,
set the engine,
remove the intake,
install the flex plate bolts,
install the intake manifold.
aside from the wire connectors going to the intak manifold harness, there are 2 coolant lines under the throttle body that need to be disconnected.
these hoses are 20+ years old so be gentle.
or replace them.
