'75

Does anybody know if these springs will work and what retainers and keepers would have to be used. I'm using the summit 1103 cam which has .465 lift and depending which article you read is aproaching the lift limit of the vortec heads. I'm trying to save some coin over the price of the comp cams beehive springs. I've also heard the Z28 springs would work but I don't have any specifics. Any help?
