Correct.
I don't know what a "regular" GP, but if it has a 60* V6 (3100/3400) then it sits off to the side on the motor with a vac line going to the TB. Any part of the intake/throttle body area that sees vacuum is fine since it's just sucking waste gases from the crank case to be recycled in the combustion chamber.
On a non-supercharged 3.8L (GP GT, I guess) it is in the end of the intake closest to the "front" (belt side) of the motor. Under the MAP sensor.
It's purpose is as I stated above. The wider end of the valve is open to the crank case and its pressures. The narrow end it open to the intake vacuum. It allows the pressure of the crank case to be released into the intake manifold for recycling. It improves engine efficiency (slightly) and relieves crank case pressure with one device.
And go to the dealer for your PCV valve. The Autozone brands made my engine start burning a little oil. The ACDelco part at the dealer was actually cheaper than Autozone and stopped the oil loss.
