Beehive springs and retainers

You just need to find the right combination of parts. Basically find a retainer that fits the spring you need with a 3/8" lock for the retainer. Then juggle installed heights with retainers, locks & shims. I have them on a couple of OEM head 360s. I really like beehives because they eliminate any potential retainer interference with the rocker arms.

I'm at work and don't have my numbers handy.
