Do you get all of this for free or what? If you arent paying for it then you might at well do what you can to it. If you want it to last you can get an oil cooler, and you can wrap the header, both get rid of alot of heat, and they run hot anyway because they have a rocker arm in them. Ignitions and such are good too. If you are looking for optimum suspension performance i wouldnt powdercoat the springs, idk how much it would weigh but it is unsprung weight and any equalls alot. And if you havent a revalve should be at the top of your list before any engine mods.
