Meh, 50/50 chance, either you do or don't.
I would have thought there would be sufficient air flow through the grille, and the air dam would only be effective at higher speeds.
Higher speeds mean higher airflow, which would mean better cooling, thus my rationale that it wouldn't make a huge difference.
That being said, you'll never go wrong with Destructicon's recommendation for up graded equipment, from a buddy's experiences with his big block powered Cutlass, electric fans would be a help as well.
That pig wasn't bad when it was moving, but idling in traffic you could watch the temp gauge rise.
