Default valve spring comparison. What would you buy?

What is better in your opinions? I got a set of ls6 springs that were included with my GM hot cam. A lot of people were telling me to get beehive springs. I thought the ls6 springs were the beehive but I guess I was wrong. In your opinions, Should I sell the valve springs that came with the cam and put in something else or just install what came with it? What would you do?

Ive done several hot cam LS1 cars and I always run comp cams 918 with them. I am pretty sure they are good for 600 lift which is more than enough considering the hot cam is only 525 lift. I had the LT4 hotcam in my old 1996 SS Camaro and I had bought the hole kit with cam,springs and bent valves pulling it to 6400 RPM.

LS6 are beehive and will work good. There are yellow ones and blue ones, but I don't recall which were for higher lift. Either should be fine.

Get the PAC Racing springs that replace the 918's. There are some posts on here about them somewhere.

dont waste mony of selling a good valve springs. the LS6 springs perfomre perfectly if you dont have a cam will lift over 560.
if you are thinkin of swaping cams for more than 560 then you have to sell it and get a set of beehive 918s ,you can find it on speedinc,tsp,WS6store.and alot more.

With the lift on a hotcam, don't even waste your time replacing the LS6 springs that come with the heads. Ther're fine! Besides the LS6 will last longer than any after market spring and won't need the warm-up time like an aftermarket spring. The only thing your compromising even a little bit is 918s may be able to rev a little higher then the LS6 springs, but probably not much.

The only reason I'd change the springs is if I KNEW I was going to a bigger cam later, because it'll be easier to change the springs before they are on the car, but really it isn't that bad doing it on the car either.

I ran 918's on a 568 lift cam for over 30K miles about 4 years ago, and never had a single one brake, nor did a single one every float.

Have Comp 921's now.

What about the TR 224 cam with .563 lift? Would that be pushing things too far?
I don't plan on swapping to a bigger cam later on. This would be it with me.
