All you ever hear about is the cam plate lift, the injector breaking pressures and the size of the pump. I've alwys wanted to know more about the delivery valves themselves and how they fit into the picture, obviouly they have to open before the injectors do but you never hear if or what should be done with them for increased power or how it affects mileage, heat and ect.
