I currently have ls6 springs for my Lingenfelter 207/220 .573/.578 118.5 lsa cam. I thought dual springs would be my best bet because I would have some insurance. I heard that the 918's have to be changed after 25k miles and are prone to breaking.

What dual valve springs would you reccomend?

I would recommend 918's. Duals are unnecessary and add a lot of valvetrain mass. Im going to run a much bigger cam than you, and I will be running 918's.

They wont break if your valvetrain is setup correctly.

With your sized cam I would prob. just run the 918s. I'd also recommend the titanium retainers as a light valvetrain is definately a good thing.

The 918's with steel retainers are MUCH lighter than duals with titanium retainers.

I was looking at the PRC gold dual valve springs, w/ titanium retainers, new seals, guides, and cromoly pushrods for 356.00. Seems cheaper than the 918's to me.

The 918's are $170.00 and 260.00 for the titanium retainers. More money than the combo above unless i am not reading something right.

Lingenfelter suggest the ls6 springs and said they are good to.600 lift. Kind of suprising to me.

For that size cam, go with the 918's, unless you think you'll be going bigger in the near future.

Hey there is such a thing as TOO MUCH valve spring. Dual valve springs on a cam that small is just not needed. With 918's setup correctly, you won't have a problem at all.
