torque setting for cam pulleys?

[f22raptor]

hi all just wondering what the torque settings for the cam pulleys are because my friend had his cam belt done at ktech and the timing has jumped because the ex pulley has spun round? must have been quite loose to spin round right?

Not really, it can spin for a number of reasons...

Contamination of the mating faces (not degreased).
Damage to the mating faces.
Damage to the camshaft threaded boss.
Incorrect torque and angle tightening.
Old retaining nut re-used.
Incorrect belt tension.
Camshaft damage.
Etc...

The inlet cam bolt is tightened to 100Nm and the exhaust is +30Nm then angle torques 86deg (+/-4 deg).
