Head.jpg appears to be a stock 2003 800 Polaris XC, RMK, etc. cylinder head, since it has the smaller diameter coolant hose connector, yet it has the bolt hole for the knock sensor.

Its the same head in all 3 pics , I believe the threads are for the bosch DET sensor, the bypass is bushed down as it was installed on a 2002 in its previous life.
I doubt I will use it so if someone needs it LMK!
