As far as beehives go, Id assume Nascar motors are running them mostly for the lightweight benefits. Spinning 8000+ ain't goona go over too well with heavy *** duals. And if one fails, o well the motors are only meant for a few races anyway. And like u also said, beehives are very capable of supporting a lightweight valve.
However, I'm not saying I'm dead safe with dual springs, but I do know there's a chance to save the motor if a dual spring goes if u kill it quickly after it fails. Basically u have no chance with singles. I no its a stretch to say one will fail, I'm almost certain they wouldnt. I no its just an ls1 stock longblock worth 500 bucks, but I would just feel much better with duals, since I'm not spinning over 7000, and I like driving my car lol. Beehives are a great choice for my application, just not for me.
Are there any duel springs that offer a little less pressure than others that anyone here is aware of?

Ive perosnally had 2 engines with broken stock valve springs and worked on many more 5.3 truck engines with them. Many miles were put on each with none of them snapping valve heads or having issues other than misfires.
Im not sure how this internet myth started but its the luck of the draw with either. One has no more safety margin built in than the other.
As far as nascar, i believe they are stuck with beehives by rule as they are the stock style spring.
You can get a dual with less pressure, it depends on cam lift though. AND valve height. Idk if those valves would have the same installed height or not, so youd want to know that for sure.

I've had several broken valve spring cars come in the shop over the years, single spring cars, that left with only a new valve spring and were good to go.
Oddly i've had much more severe damage without broken springs. From over revs for example.
To each his own, just my $0.02, surely not wanted though lol.
