the part number is 12480033. that part number is the kit from Gm performance that comes with new valve springs. DO NOT USE THE VALVE SPRINGS FROM GM!!. the springs from Gm are the stock 2004 Z06 VETTE SPRINGS AND THEY CAN ONLY HANDLE UP TO A 525 LIFT. given that information, if you over rev-ed the engine 100 rpms, your springs would bind, so we circumvented the problem by installing Comp Cams beehive style valve springs with caps and retainers. any more info you would like??
