Believe the Intake Manifold on the 99/00's, though still a PI intake manifold, has the plastic crossover that is prone to cracking. Probably easy enough to just swap the 02 manifold over though. Otherwise i'd be sure it's the same (romeo/windsor) as yours and whatever else anyone who posts after me says. My belief is that besides the manifold crossover it should be the exact same engine down to the core.
