Hot under the hood and collar

Hi all. I am in need of some serious help with my Jeep Cherokee Sport.
She is a 1995 Sport 4x4 4.0 litre. I have poured over $4,000 into the engine and components over the last 16 months. I purchased a rebuilt engine and many other new parts and still can't get it to run properly. All cooling components to include radiator, hoses, thermostat, & fan clutch have been replaced yet she keeps overheating. It is mostly when I drive around town.
Below is a list of new components.

TPS, MAP, IAC, CPS, Water Pump, thermostat, Distributer, all hoses and belts, Fan clutch, plugs & wires, oxygen sensor, oil sending unit, heat sensors, power steering pump, fuel injectors, fuel filter, radiator, and I am sure there is more.

The engine has just under 6,000 miles since I purchased it from a local engine reman co. in Glendale, AZ.

I can only think of two things that would cause this problem in light of all of the new components on this vehicle. 1. the static timing between the crank and cam are one degree/tooth off, or 2. the head is not the proper one for this engine.
My reasoning for the latter is due to the fact that the original head had 2spots for temperature sensors. One for the guage in the front of the head, and one for the computer at the back of the head. When I spoke to the reman co, they said this was the correct head, and to put the heat sensor for the ECU in the block.

Any help would be greatly appreciated as I am at my witts end and ready to sell the thing and start new.

Couple silly questions. Do you have a fan shroud? Did you bleed the system properly? And does the e-fan come on when ac is on?

I'm about to run into the 1 sensor and two plugs also. Purchased a newer 4.0 and when you posted I thought I'd look at the two heads. What do you know they are different!

Thinking about how to adapt since I don't wanna pull the head.
