These springs will change the timing characteristics of the exhaust valve opening. A heavier spring will keep the
valve in the closed position longer, while a lighter spring will allow the valve to open sooner. NOTE: If making any
changes to the valve springs make sure to change all springs so that each valve spring is the same.
