[Closed] Stumpjumper S works headset???

I recently bought the above frame without the H/S. Does anyone know what replacement aftermarket H/S will do without having to purchase from Specialized.
I've done some digging and cane creeks name came up, but I don't know if this is the exact H/S I need. Think it was a IS 2 that was mentioned???? Details below..

The above doen't mean a lot to me, but would be grateful for your advice if it does.
