None of your bees wax....
Lol! That's what cam companies have told me.
I think I have the numbers here somewhere. Let me look.
This is what I have:
Comp Beehive springs #26986-16
Retainers #975-16
123# seat 284# @.500 lift.
(stock 340 springs were 96# and 242#)
Comp Beehive springs #26986-16
Retainers #975-16
123# seat 284# @.500 lift.

You will fain little with beehive springs on most applications.
Need more info on cam type, max rpm etc. There is more than likely is a BH spring to do the job, as the range keeps expanding. Also look at conical springs such as the Comp #7228. The reduction in valve strain stress by using BHs is worth it in my opinion. In a BB build I am doing, will be switching to BH springs.
Thanks Toolmanmike, for the Comp Cams part numbers, and also thanks AUSA66, PAC may also have parts that fit.
I haven't decided on a cam yet, or even that I want beehive springs. I'm building a moderate street 273. I'll be using a flat tappet hydraulic cam with sort of middle range duration and lift, and probably around 110 LSA, for a torque peak at 3000-3500. I was just reading about beehives and went looking to see if they were even an option for an LA with 3/8 inch valves. I didn't find anything, though I guess I didn't search very well.
Conical springs are also interesting, though I don't know if they're really better than beehives or not. Not that I'm expecting that beehives make much difference. Thanks again to everyone who responded. If anyone knows of any more, keep 'em coming.

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.

Looks good! Comp rockers?
According to my old highschool buddy that owns an engine shop, that I asked to identify them for me, yes Comp Cams rockers. I have no details on this 340, other than I better have spare tires for the Wife in short time...
Beehives could prevent this. Something I need to change someday. Comp 901's would probably help.These springs were "340 springs" from E bay. We shimmed them up and made them work but they are short.
I'm glad that you mentioned conical springs BEEcause they seem more appealing for reasons of harmonics and mass of the valvetrain assembly. My plan includes a solid flat tappet cam, and tappets in the 80-100 gram range. They have the edm lifters over at Hughes website that are pretty light. If I remember correctly the comp solid lifters weigh in around 120g.

Comp, Crower and Hy-lift Johnson (all the same as far as I can tell) are all 95 grams...just put my scale away.
