well i've managed to get some new seals, the air adpater and a valve removal tool. However the tool that was recommended to me isnt available at my local machine mart so they sold me another one. It clearly says on the front of the box "tool removes valve springs without removal of the head from the engine". This is however is not the case, the heads gotta come off for this one to work!! Muppets. Gonna see what they can do when i ring em back.
Back to the job tho, what will i need to do to ensure the timing is right when i put it all back on?

??
Cheers to everyone for the help, i'd be lost with out ya!!!!!
