I did have this issue before with dual conical springs from Comp. They told me to use the dual conicals for a solid roller cam but the catalog says they are only 150 on the seat. We went ahead and got the dual conical springs and they measured 200 on the seat, plenty on the nose and the coil bind was just right. So the guy was right, the catalog was wrong and the springs worked great in that engine.
That is odd that the actual vs catalog are that far off. But since you have the springs, test them for pressure and coil bind height and see if Kaase is right or wrong. I would use 0.060" before coil bind for my calc.
