Made a new thread for this so searching it out would be easier. Had the idea of using these springs (4.6 beehives off a Mustang) because they were stock beehives (as in readily available and affordable).
As it turns out, their numbers were real close to Kiggly's spring numbers.
Brand new kiggly's (these numbers were generated off our stock height numbers. They were not done with the lower cap of the Kiggly's because I would not be using them. It was basically so that all springs could be an apples to apples comparison);
63 @ 1.575 and 140 @ 1.240
The stock 4.6 beehive springs;
72 @ 1.575
140 @ 1.240
So just slightly stronger than the stock 4G63's at close (66 @ 1.575) and matching the Kiggly's numbers open. I can live with that.
But now to make them fit. First I tried using Evo keepers and retainers (these will match up to our valves but it places the spring height at a different/lower point. You could also use our keepers on an EVO retainer but that would make the spring height even lower when closed).
I noticed that the stock 4.6 retainer was just slightly undersized for the top of the beehive spring (don't know if you can see it. The EVO retainer is next to it);

But the EVO had the same exterior dimension so it also sat the same;

So I felt safe using the EVO retainer. Unfortunately, when I finally got the keepers in there, the spring height closed was just too small;
![]() 
You can see from the side angle that the EVO retainer side sits much lower than our stock (that's what I put on the other valve shown. Actually its a 4g63 but the same height difference as ours). So I knew it wouldn't work. But I tried to spin a stock cam for the fun of it, and it got bound. So no go.
Then I tried our retainer on the beehive and it would not fit. The shoulder on the bottom of the retainer (that helps center the spring), was ever so slightly too big. So thinking about cost effectiveness, I thought the cost of turning down the retainers and buying the stock 4.6 springs was still much, much cheaper than getting Kiggly's, so I continued on. I turned down the shoulder on the retainers to fit the top of the beehive spring;

Lol, not a real good picture but what I did was simply take a grinding wheel to the retainer just to make it fit (obviously, these would be turned down in a machine  ).
So from there, I just installed the stuff and the spring height came out equal to the stocker height;
![]() 
So I then took my biggest cam (crane 28) and put it on and spun it to check for bind;
![]() 
No bind problems.
Now the math on the bind (as far as measurement comparisons), puts the bind on the Beehive slightly sooner than our stockers (I can't find the numbers right now, but you're welcome to look them up, lol). Oddly I came up with the same bind point on the 4.6's as the Kiggly's. So, imo, by the numbers and by use of as aggresive as a cam as we have out there, it appears that we can run these on our cars.
There are a couple more things I want to check on. First off, do the stocker 4G63 retainers have a different/smaller shoulder on it adn would I be able to use them? Doubtful, but its such a small difference that its worth it to look at.
Also, I have not run anything here! I really have no proof (other than what you have seen) that this will work. While I don't see any problems and the evidence certainly supports using these. I can't guarantee it it yet.
Just some interesting stuff. Captain Caveman
