If you use the 8005A springs and go to 10-degree locks and retainers, the retainers are: Comp Cams 748-16 and the locks are: Comp Cams 612-16. Assuming the valves on the 700SCI are the same as the 525EFI, which I believe they are, the valve seals are: Comp Cams 515-16.

One more VERY important note. When you change the rockers, be sure to reuse the existing rocker stud nuts / polylocks. Do NOT use the ones that come with the Scorpion rockers. The OEM nuts are shorter than what typically comes with new rocker sets and the valve covers will not clear if you don't reuse the OEM nuts.
