Boy you are persistent aren't you. I asked for firsthand info so I wouldn't have to deal with someone like you. I don't care what you think I should do or what you buddy does. This stuff is my hobby, I try to have fun with it, life is short. If I want to try running those lifters I will, you or nobody else will sway me otherwise, UNLESS you personally have tried them, or have firsthand info, so please,
for the love God, go lap some valves, or read your dyno sheet.
