Valve Training
Coil-bind is a major concern when using a high-lift cam. The first thing to do is to gently check the spring's actual compressed, coil-bind height in a vise. What you may find is that the spring checks around 0.030- to 0.050-inch shorter than the published spec. If you use the measured spec, you must check every spring and record each compressed height. Minimum coil-bind clearance is 0.060 inch.
