Installing Icon alignment cams

[cbenn]

Need some help, I have the Icon 2.5 coils and in the process of installing them, the kit comes with new alignment cams, the directions say to install with arrow pointing to front of truck, there is no arrow on these cams, just the slot and the letters SPC on top of cam, for those that have installed them what direction does the slot go? Any help with this install is appreciated.
