Use your intake, exhaust manifolds, and the EGR pipe from the passenger manifold, to the intake. The 98 intake will also be missing one of the coolant temp sensors you need.

Pull the engine first, then work on getting the parts you need from it off. MUCH easier working on it where you can get to everything easily.
