Kiggly Beehive Valve Springs Vs. The rest
They say that their beehive can be run using the stock retainers
The Kelford is a pretty aggressive cam..if you ran an smaller HKS cam and weren't planning on revving past 7k I would say you might be fine. Why risk it though..I believe I sent you a PM on SCE

Sure man you can..Will you float a valve, why risk it..If your going to be revving past 7k valve springs are recommended especially for an aggressive cam.

If you are trying to budget which it seems like, i wouldn't try it on something like this, not worth the chance..they said change STOCK VALVE TRAIN if you plan to rev over 7k period. So with an aggressive cam, and you want to rev to 8k, yes i would get springs and retainers..
Go on every website that sells Kelfords..go on Kelfords website..they said recommend to change springs and retainers..I don't know what numbers you want. hope it helps..

I set up the spring pressure and installed height to be at the high side of a happy medium and also allow for 0.500" lift. There are plenty of people running around with springs at ~100lbs on the seat and no wear problems from other manufacturers, so there is no reason my springs would have any more problems than somebody else's for wear. DSM supertech stuff is in this same installed pressure range and they are a very common spring.
The trick thing with the beehive setup is it allows a lot lighter retainer and the spring itself has a lower effective mass. This translates to about 500-700rpm higher potential before valve float for the same installed pressure and spring rate as an average dual spring.
The springs I sell were tested against several other springs on a cylinder head only test stand with high speed video, looking for which springs had the best behavior during surge. I picked what I found to work best. I found some that did some really ugly things that I didn't expect before testing them.
Durability-wise, I also ran them on the test stand sweeping between surge and float rpm's on a very aggressive dsm cam grind (all 8k+ stuff) for 30mins straight and saw no loss in seat pressure or rate afterward. One customer ran my springs for an entire season going to 10,500rpm and with his 2-step set in the 8k range on some relatively large cams and saw no change in any pressures after the break-in period was over (they will change maybe 5lb on the seat during break-in, all springs do). This car in particular was running dual springs and tossing rockers while on the 2-step and beating up the other springs regularly.
Shoot out any specific questions you have and I'll do my best to answer them.
