Alan is right. There is a huge difference between actual spring pressure, and using checking springs. We've seen as much as .050. But that being said, if you get a min. one way, don't assume that min. applies when using actual spring pressure. In other words my min. is .035 intake, .080 exhaust with checker springs. I wouldn't use those numbers on actual spring pressure. At those settings I have seen the shadow of the exhaust valve in the piston. Other guys may have a very different take on this.
