6.1 Valve spring failure

didn't checked it out but is there a seat/retainer for the valve bottom? Or are the clamps of the damper the seat? In the case if I use the other springs from above w/o damper do I need a retainer below the valve to avoid valve movements sideways?

aaargh, are shims and retainers required? this never got answered..... I simply threw the stock ones out and replaced them with the 1511. without the cages of course...
