well you see the timematic conversion of the thirteenth neo is greater then the torque of edelbrock... so no
Headers, with free flow exhaust system will help.
there are some good headers and exhaust out there like a flowmaster for the 200o will give a extra 25 horsepower for 400 bucks and headers will give about twice that cold air intake, high flow cat, pulley system, headers, exhaust. also aluminum driveshaft will reduce weight and allow more power to the wheels and better rear gears will help get more power to the ground.
To increase the horsepower of a diesel engine you need to put either a turbo charger or a supercharger on it. Cold air intake will also help.
Headers are aftermarket replacements for the exaust manifolds. They are the parts bolted directly to the heads on the sides of the motor. They channel the exaust from each cylinder down to the exaust pipes.
Maybe 10 on its own. With other mods like a bigger throttle body and exhaust it will help out more.
Headers help the engine breathe better thus better performance but the rest of the exhaust system needs to be included.

They help the engine "breath" better.
Headers help to maximize exhaust flow which allows your engine to run more smoothly and use less power per stroke. Because of this headers can improve fuel economy but the change is very small.
190 Horsepower which is stock for this engine. The K&N filter will add almost no horsepower at normal driving rpms. It will help some but only at higher rpms, which is a range that you will not be driving in. These type free flow filters only help in a racing environment, and do almost nothing for day to day normal driving. As to the TB Spacer, it does nothing to increase horsepower. I know you have more than likely been told that they add horsepower, but the dynos do not lie, and they simply do almost nothing for a no-race vehicle.
Having the exhaust valve still open when the intake starts to open uses the exhaust "pull" out the exhaust port to help start the intake charge entering the chamber -- before the piston has started down and has generated it's own vacuum. Also, leaving the valves open longer (duration) increased the density of the intake charge and allowed the headers to better scavenge the exhaust gasses out.
They help with situations where you are trying to fit unusual or tight applications.
