What are the absalute best single beehive springs?
I am wanting to run a 224r cam or something close. What are the best, most reliable, long lasting single beehive valvesprings I can get for this cam? I want valve springs that will not break and will go close to 100k. Like 60k and up.

What type of lift does the cam have?? I don't think you will find too many people recommending valve springs to 60k+ on a .580+ lift cam unless you don't plan on too many WOT runs...and I seriously doubt that is why you are modding your car.

PAC 1518 is a nitrided version of the 1218. Its 'rated' for .650 lift, but all that means is you can expect a certain life at that lift. If you run it with a lower lift cam you can expect the life to be higher.
I'm going to be using 1518's with a 224R as well.

PSI 1511 Maxlife. I've tried them all. This is the exclusive beehive I use now after having tried them all, and they have a 0% failure rate. These springs will take .620-.630 lift without shimming. Will go upwards of .660 with different heights. This sprin is also Advanced Inductions exclusive valve spring for 90% of their applications.
Here's the company:

Like Damian said the PSI stuff is hard to beat. PAC stuff works really, really well also. It's hard to go wrong with either 2 of these spring company's, given your cam size and expected duty cycles.

I personally wouldnt consider pushing push any spring to 100k miles on an XE-R lobed cam. It may be small, but those lobes are pretty aggressive. Im not saying it CANT be done, as long as they are treated right, but it would still be a good idea to check them every 20-30k miles to make sure they arent losing any pressure.
Ive lost 2 sets of 918s (my fault.. I pushed them too hard, too long), so I know all too well what a broken spring does to an engine.

I agree. I have also corresponded with someone inside GM and this is the spring they look to for their personal builds. I have installed several sets and they are excellent and often overlooked likely due to lack of internet hype. You need to figure out the required seat value and then shim to attain that value while keeping track of clearance to coil bind, etc.
