The heads primary job is the mixing of fuel and air and delivering this to the combustion chamber.
Any turbulence or drag can restrict the air flow into the engine starving you of power. So this TorqueCars article will focus on the intake valves and how they can be improved.
The aim of head tuning is both to maximise the amount of air and fuel that gets into the engine, and to improve the mixture.

How to add a turbo to a non turbo car.
The basic reason for forced induction (turbo or supercharger) is not to increase compression or the maximum pressure in an engine cylinder, it is to increase volumetric efficiency (the efficiency of the engine at drawing in air) although forced induction is the most effective method of upping compression.
In computer games we just tick a box, and within seconds our car is fully turbocharged and running much faster. In the real world things are very different.
Suspension settings, lowering and stiffening
On the track your priority is fast cornering and suspension plays a large part in this. Track conditions are quite forgiving and you can make some compromises like using hard suspension and lowering the car for optimum aerodynamics and a low centre of gravity.
This works well because tracks are fairly flat and you do not have a carrier bag full of eggs in the car from your return trip to the supermarket.
