Well, if you are running a cam with .560 lift then use the recommended springs for them. Every cam has a recommended spring that you NEED to use otherwise you risk them binding, breaking and/or floating.

Doc,
Your spriing pocket size makes a difference,t ake a gander through Comp, etc, and match a similar cam for you setup (assume hyd roller) and see the recommended springs...pay attention if they are 1.25 diameter vs larger diameter.
Then head to Jegs/Summit, etc, and price'em out.

I'm looking at a Comp Cams 224/230 .560 valve lift and its a hydraulic roller cam. BTW: I am running AFR 190cc heads.
The 987 dual springs are recommended by Comp Cams. pg 338.
