Generally headers create more problems than they are worth, some require special spark plugs or you can't get the wires on. Others burn the wires, some you have to loosen or remove the headers to get the plugs out. Most leak because the bolts loosen up. And many have a tinny sound. Also, you probably won't notice any appreciable performance with a stock engine.
Get some stock rams horn manifolds which will last forever or get a good aftermarket set made by Dorman. Jegs sells them.
