The increased duration of a performance cam with an aggressive grind forces the valve to open and close at a much faster rate. This rapid opening and closing at high RPM can cause "valve float". Valve float is the inability for a valve spring to close the valve fast enough to avoid piston contact. When buying a cam through BMP design's webpage or through a sales associate you will be informed of the correct springs to use.
