Damn if it isn't one thing it is another. As 440 Offroader pointed out, if you are using stock rocker arms it is unlikely you have a true 1.5 ratio. That still does not excuse the slop work that has been done. I learned the hard way on a set of small block "x" heads that you have to be very careful with choosing a machine shop. Problem that most of us will learn the hard way unfortunately because we don't build engines every day.
