The cost of the head and base gaskets for the 400 alone would be about £80 plus the chain and oil seal and all that work. If the engine is good and running well why take it apart when you do not need to.
I have replaced the cam chain on the 600 and the seal on the 400 with very little difficulty and very little time compared to a full engine rebuild.
A few important tools required for either job would be:
Rotor holder
Rotor puller
Torque Spanners, at least two, one 0 to 20 Newtons and the othe 15 to 50 Newtons. (A third 30 to 150 would be usefull)
