All in all its a pretty straight forward job and should be easy enough if
you are handy with tools and have some mechanical knowledge. Only thing I
have had issues with is getting the exhaust cam one tooth out on reassembly
but if you mark all the pulleys using nail varnish or something and mark the
appropriate location on the block/head too and then check check and recheck
after assembly you should be fine. I usually pop the spark plugs out and
wind the engine over by hand a few times after installing the belt and then
recheck the belt tension before starting the engine too.

Good luck!
