From some of these discussions, it seems that people think all cams have the same ramp design, which is not true. We just recently had a discussion that the valve should open and close at the point where the lift curve starts to take off (see link below). You can make small variations from this for tuning purposes, but you have to be careful. I once ran too much lash on a very aggressive cam. It ran like a demon, but not for long. The result was a broken rocker shaft and 5 bent pushrods. As for hot or cold settings. I have not done any systematic measurements, but have not found a big difference for our engines.
