The Lunati Voodoo 60102 is not that radical and won't need much more than 5500 rpm for best performance. Try just running the outer springs.
if that not enough spring pressure for the rpm you want to rev it, install the inner springs too and give'er.

If you were running one of the bigger duration higher rpm voodoo cams I'd surely use both outer and inner valve springs for best rpm capability after first doing the initial break in on the outer springs only.
