Which dual springs?

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.
