All worked prior to the head being worked on. After that fans just completely stopped working, only when I jump the wires is when I know the circuit was working and thought they were the sensors but even after sensor replacement, no results.

I believe you do not understand what I am trying to tell you.
The coolant not running at the radiator neck could mean the thermostat is not opened yet though the reading could be high. Get a scan thermometer to check the engine temperature to confirm it is not overheating.
At the thermostat housing fan thermo switch, disconnect it and use a jumper across it to let the fan run full time when engine is running.
Note the temperature reading.

I undersdtood the question, I was responding to the last portion of that question (When fans kick in, does it stop running after a short while?) As for the ground curcuit, is it the one that is like a white/clear type little block type that has a few grounds routed to it mounted to the inner passenger side engine panel by wheelwell(wheelhouse as you called it)? How does that get tested? Looking at it before, I noticed that a few grounds connected to it to like a branch type connection that is eventually bolted to the side wall engine bay, If i'm thinking this is what you are mentioning? Had the engine scanned and engine is not overheating, just wrong readout. Grounding issue on the sender wire to readout. Not sure all of a sudden this happened after head swapped but hey, car is 20 years old. Guess it was matter of time.
