On some overhead cam engines, valve shrouding occurs when the edge of a valve is in close proximity to the combustion chamber wall, making for a tight squeeze for air to travel around the valve in this area. Some hot rodders will try to increase this gap for better air flow in this area. They call this unshrouding the valves, or it is also refered to as relieving the valves. Valve shrouding will usually restrict flow through the valve at some point in the valve lift, but not always. The example below was flow tested on a Valve shrouding will usually restrict flow through the valve at some point in the valve lift, but not always. The example below was flow tested on a
Flow Performance equipped micro bench which showed the biggest gain on the intake valve was at .400" lift with a gain of 8 cfm. While there was about a 2 cfm gain at higher lifts, there was also about a 2 cfm loss at lower lifts.
