It's like having too much ignition(or blocking the heat crossover) ..It will help you if you use it, but it's not necessarily a must have. They do reduce wear, extend life, and help keep the heat where it belongs, but they also cost a little for each application. Will you feel a boost? not like a cam swap, but you may notice less tendency to detonate.

Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
