not really much to worry about apart from the timing belt + tensioner, new cap, arm and sparkies is advisable and have a good look at the leads. Check the alt & pas belts for wear/cracking, might as well do the rocker cover gasket as its only 8 nuts and cheapy! Oil+filter obviously, make sure non of the sensors are leaking oil.
Apart from that make sure its got the right dizzy on it, but since you say it came out of a MK2 then it should be ok, just make sure its a digi one if you're running it on digi or a k-jet one if running on k-jet.
