I replaced mine last year using a Ford Racing manifold and Felpro gaskets.
I'm not sure about the part numbers, I'll see if I can locate my receipt.
I replaced the water pump, alternator, serpentine belt and all hoses including the heater core hoses and the coolant line under the manifold.
I also had my fuel injectors serviced by Cruzin Performance
Also, replace your fuel filter at this time since you'll need the same tool as the fuel lines under the hood.
I labeled every connection that needed to be separated on both sides so nothing would be missed during re-assembly.
