This is a Caterpillar 3406E / C15 style cylinder head we did a valve job & surface to. The surface of the head was warped so we mounted it on our Rottler multipurpose CNC milling & boring machine. After we got the surface flat & square the valve recessions needed to be adjusted back to Cat specs so the valves were removed for cleaning & grinding.
