SS Div. 6. I, too, thought duration was the culpret. When you allow the valve to stay open longer it must close rapidly or there could be clearance problems. Doesn't excessive duration cause some of these problems stockers are having? I do know if your ramp design allows for quick closing, the spring pressure has to be increased or that valve will bounce. Wouldn't you say all these things are the root of the rocker arm problems? And then the roller rockers and girdles will solve everything until they remove the stock lift rule then the Jesel system will be necessary. Where does it stop? Your posts are excellent, by the way.
