I did a few heat cycles on mine before I drove the car and had it tuned after the cam swap

Q. What is the proper break-in procedure for new valve springs?
A. It is important for new valve springs to take a heat-set. Never abuse or run the engine at high rpm when the valve springs are cold. During the installation process use COMP Cams Valve Train Assembly Spray (#106) on the springs, rocker arms and pushrods to supply the necessary lubrication for the initial start-up. Upon initial start-up, limit rpm to 1500-2000 until the temperature has reached operating levels. Shut off the engine and allow the springs to cool to room temperature. This process will help eliminate premature failure and prolong valve spring life.
