generally on cars you don't drive very often that have extreme valve springs with a big cam(granted i have no idea how big your cam is) you change the springs once a year. From what I hear with the car sitting for long periods with some of the upgraded valve springs fully compressed they tend to become fragile. On race engines the rockers are often released after racing is done to take pressure off the valve springs while the car isn't being used. All of the previous things stated are gathered from info over time, some maybe true, some maybe false, just something to think about. On my built gto i ran very similar springs and put 28000 miles on them with no problems but it was all in 1 year and then changed them after a year because of the things i previously stated
