Dave Crower designs the cam ramps to slowly set the valves onto the seats - this way it doesn't hammer the seats into the heads. He told me that with the runner volume of the 186's you have to get the valve up quickly and hold it there as long as possible in order to get the air in and that the velocity and VE would remain high because of the small runner cross section.
