How To Lap Valves, Spring Height Micrometer, and Reface Valve Stems [EXPLAINED]

Having the right tool for the right job will always save you time. A Spring Height Micrometer comes in very handy when you do a valve job or change a cam and springs. We used our Makita drill to lap the valves on these LS heads and then installed new springs. After lapping the valves in we made sure to reface the valve stems as well where the rockers make contact. The Spring Height Micrometer made it easy and fast to accurately check the max spring height on each of the valves. All of our measurements were within 0.020 (twenty thousandths), so we didn't need to shim any valve springs.
