When you get to the re-build stage:

Plugs out. Cam belt off. No followers or T vents.
  Crank the engine until you get fresh oil out of all 4 T vent drillings.
Re-fit T vents.
  Crank until oil appears at all cam bearing oil holes and cam follower oil      holes.
Set crank at 60 deg BTDC, do not turn again until belt is fitted and timed correctly.
Re-fit followers and cams, fit cam sprockets (you will need help)
Fit belt and time-up etc.

Dont forget a THIN smear of green sealant under the front edge of the front cam bearing caps. (degrease the caps and head first)

Excellent advice, thanks  :y

The vents between the cam bearing oil holes I think are (see red dots):



Not sure if they were exact.. but i rember seeing tiny holes around that area in each hole, its these that should be clear?

Do they lead to the next cam hole?? Could i poke a straight paper clip though it? to help clear it?

The red dots indicate the oil feed holes for the cam followers, the small holes next to the cam bearing cap bolt holes are the oil feeds for the cam bearings.

Dont poke paper clips into any hole in a bearing surface, its so easy to raise a slight burr that can then 'pick-up' and lead to seizure.
If you cant get oil to come out of all the holes then try flushing out with WD40 or carb cleaner. If you must poke something into the oil ways use something like a nylon guitar string or even 7/0.2 pvc insulated wire.

instead of a nylon guitar string or even 7/0.2 pvc insulated wire i have heard that good 100Lb sea fishing line if good for checking the oil feeds are clear, as its nice and strong but also very flexible
