Fit the camshaft wherever it lines up with the cam sprocket, then put the engine to TDC, make sure all the timing marks are in the correct position, then install the rocker gear, then you should be in bussiness.

+1, only need to worry about TDC if you are reinstalling the head with camshaft and rocker assembly as a whole.

From what I remember, I believe you have to torque the bolts to AU spec since you are using the AU head gasket. Not 100% sure though so you might want to wait till someone agrees or corrects me.

What you would do is set the engine to TDC and then check that the timing mark on the cam sprocket is in the right place.
Not sure why that's a hard to think of?? It's kind of the next logical step.

Did you cable tie the chain to the cam sprocket?
If you did then the sprocket only goes on one way and the timing should be retained. If you didn't and you've rotated the crank you going to need to remove the timing case and check the timing marks on the crankshaft and aux shaft sprockets line up with each other.

This pic should help

Or

He could remove the dizzy cap and rotate the crank untill the rotor is pointing at number one lead and the mark on the balancer shows TDC

That's fine if the chain hasn't moved on the sprockets. But yes worth checking there before removing the timing case

If the chain has moved on the sprockets the rotor position and balancer mark won't line up at the same time. It's also possible to jiggle the chain to fix it if need be. It's worth try for 30mins before going through timing cover option.
