Valves are made from 214N Stainless Steel Valves are designed with a wasted stem for increased gas flow. Valves are CNC machined Exhaust Valve 45.5mm head size 3.5mm oversize This is the biggest valve you can use in a Pinto without offsetting the guide we have also put in an extra cotter groove so you can move the springs up or down this helps when setting the spring height. We also put a stellite top on the valve to stop the follower from wearing the valve top when it drags across the valve when using high lift cams
