MB 126 380sel, new cams or engine swop ?

HI!
I just bought a MB380SEL 85´ in Munich this friday. Very nice and clean car but it has the weakness of damaged cams and valvehydroes (288.000km.). It has a 2-way catalysator and Niveaumat suspension as well
as a full leather Recaro classic seats in nice cream colour. ABS as well as Airbag and safetybelt tighteners.
I would like to know if it is recommendable to rebuild the engine top with new cams and valvegear. Or would it be better to change to a 420 or 500 engine. If the latter sugestion, then what about the electric equipment, wirering and stuff. Would I have to change a lot of part besides the engine.

I would appriciate any hints or answers on this topic.

W126 series with gas V-8s are known to experience cam wear with high mileage if oil changes were not conducted on schedule. These engines also require valve jobs around 200K to eliminate oil leaking into cylinders around the valve stems. Third, if the engine still has a single cam-drive chain, you need to replace it with a double chain and new guides. With 288K, you may want to think about having your engine rebuilt from the ground up, which will also include new bearings, rings, etc.
