There are two differences. One being the cam is slightly more sporty, and the exhaust valve is around 2mm larger, everything else is the same mechanically.

Electronically the XR6 gets more fuel, and sportier tuning, if auto it has different shift points also. Otherwise theres next to no difference really.

XR6 puts out 164kw standard

Almost correct. (AU Falcon std compared to HP (not VCT))

Cam is different
Valves are the same (not larger on XR/HP) (valves are same size on all AU I6 engines
Fuel pressure regulator is set at higher pressure on XR/HP
Combustion chamber is different shape
Intake ports are different size on HP/XR
Pistons are the same.

The valves were bigger. Thats why the combustion chambers were different.
