OK, I have a question. People refer to these measurements as "loose" or "tight", assuming that the larger measurements mean loose and the smaller mean tight. I always assumed that meant the valve didn't open very much when tight and opened more when loose. However someone explained to me the opposite is true, what we are measuring is valve LASH, the distance between the tip of the lifter or cam lobe and the rocker arm? So that a wider gap means the valve opens LESS because the lifter/lobe has to move further before it contacts the rocker and moves the valve. A smaller gap means that the lifter/lobe contacts the rocker quicker and therefore opens the valve MORE as they move through their travel. Does this make sense?
