If it's already off, take it to a machine shop - but do your homework.

For example, I can get a set of heads cleaned, checked, tested & resurfaced for $250 at one place, $400 at another, and a whopping $700 at yet another shop; and the kicker is, the first shop puts out, by far, the highest quality work and has the best equipment (and the most experienced staff).

If you can't find a shop that specializes in MB's, head down to your local speed shop and ask who they'd recommend for real high horsepower stuff - ford, chevy, whatever; then call them. Odds are they'll have the people and know-how to do whatever you need if they've been around long enough.
