I'm 16 years old and did the head gasket on my 250 before having to pull the head again and found a cracked block in which I did an engine swap and put my original head on the "new" engine. I've been working on Mercedes for 7 years so I do know a thing or to but the job is mainly just time consuming and risky if your inexperienced, although no special tools are really required.

The only special tool I needed was for pulling the timing rail on my OM617 which I fabricated out of $5 worth of washers and a bolt. Let me know if you go ahead with the job and I can give you detailed instructions on how to make the rail pin puller.
