dual valve springs

Considering replacing 1.677 manley triple springs to lighter 1.5 dual springs for my super stock 520 heads. Installed height is right at 2.050 and could get it to 2" if needed. Looking for recommendations regarding PAC's, Manley, comp or others. Understanding every application is different, how many runs can one expect from the dual springs and how are the springs holding up? Wanting if possible something that would last longer than 35-40 runs.
