I did mine when I got it and I remember the job being refreshingly straight forward with the only odd bits being having to drain down the coolant and pull the upper radiator hose and maybe keeping the distributor timed. I
What I remember about the job...
I pulled the hood which gave great access to the front of the engine.
I'm sure I didn't clamp the cam sprockets in any way. Usually the cams stay put if the marks are lined up properly. Be warned though, if you have them in the marked position and you move them several degrees in one direction or the other, the spring pressure from the valves will snap the cam to the next low spring pressure position, possibly knocking a valve into a piston. If you are not clamping the cam sprockets, be sure not to rotate them at all.
I put a dab of white paint on the cam timing marks and the crank pulley some times though in the case of the 907 the crank pulley mark was very visible.
If the bearings on the tensioner are anything other than perfect, replace them. It is a simple matter to press in the bearings (on the tensioner with replaceable bearings) and a seized tensioner bearing will destroy a timing belt in short order.
I didn't look at the video tony referenced above, but I'm sure it has as a penultimate step to rotate the engine over until the timing marks line up again to make sure everything is good before attempting to start the motor.
Don't be in a hurry to get done, and you should be fine.
