I don't really see any problem in this thread. Dave got some bad advice, or at least confusing advice, about valve lift and power so he asked a question. He got a pretty clear answer that less lift isn't going to make more power. He also was told that more lift may or may not make more power. Basically the answer in this thread is the same answer to most questions on this board, "try it and find out". Engines are complicated and nobody knows what will happen on any particular engine when some part of the combination is changed. Guys that spend a lot of time in a dyno cell or at the track are constantly getting surprised about what works and what doesn't work. On Dave's engine I can guarantee that less lift isn't going to make more power. My guess is that more lift might make a small amount of power but I doubt it would be worth the expense of new rocker arms and springs.
