Correct thread reply, show some things how to help keep the engine bay heat down. Headers are like multi tube radiators, radiating heat up into the engine bay adding to people's engine overheating problems. The manifolds send the excessive heat out to the back of the car.
Want your engine to be running in the 180* to 200* degree range, anything more than that and you are asking for problems. Want your radiator and cooling components to keep engine temps down into the recommended operating range.
