Thinking about getting this 97

Cam and crank sensors, coils help big time(which is fairly specific to mine with COP)

An extra MAF couldn’t hurt either though 99.9% of the time a “bad” one just needs to be cleaned
 
Got the Dorman intake unit and I've got a question about it.

Is the rear coolant passage supposed to be blocked off? I thought that there was a crossover coolant passage on the rear of the intake manifold as well?

It’s just a plug with a clamp you can remove. Dormans are one size fits all so to speak so they’ll come with plugs like that one as well as the screw in ones on the crossover depending on application.

In your case you want both front crossover plugs removed for the PCM and gauge ECT sensors and the heater core one removed

This is the specific area I'm talking about. You can clearly see it's blocked off and there is no coolant passage going from left to right sides of the engine (heads). And doesn't there need to be two nipples coming from the back for the water heater?

That port on the back of the driver's head doesn't do anything. The heater core is fed by coolant from the top of the rear of the passenger side head, and returns via the valley hose to the water pump.

This design is a part of the reason why cylinders 7 and 8 tend to run hot, and the issue that prompted the apten cooling mod.
 
So what you're saying is that this intake manifold is correct and can be used safely, @theterminator93

I knew about the rear two cylinders running hot, but never knew exactly why. I knew the mod existed, but never realized how it was performed.
