Egr Removal
Im replacing the head gasket on my 90 7mge and would like to remove the egr but don't know if it will kick the cel on. The car is from PA and not a Cali car. Also i want to know if it is a bad idea or not. It would be nice just to clean up the engine bay a little

It's a stupid move given how the kick you'll see in combustion chamber temps, reduction in spark advance and reduced mileage... but, if you must you should source a JDM ECU, it's tuned to run richer and with less spark advance to compensate for the higher engine temps.
And, no, deleting the EGR will not cause any diagnostic codes in any 7M model except for the California spec ECU.

I don't understand your question...
Exhaust gasses come from the exhaust side of the head, run through the EGR cooler and then through the modulator valve into the intake.
