hi, i think these are quite straight forward id say go get a haynes manual and follow that through, you have to remove the cambelt, viscous fan, front grill, cams, push-rods, inlet and exhaust manifolds remove the valves and guides etc then get the head crack and pressure tested.
if you aint pretty savvy with a spanner get someone to do it for you as itl just be a pain from start to finish and you'l end up having to replace pushrods if the cambelt snaps!!!!!
