If you can not get a pair of vice grips around the bolt head you are in for a bit of an ordeal. Try cutting the bent part of the correct sized Allen wrench off. Grab the strait shft with vice grips, insert the shaft into the Allen head and start tapping with a shop hammer. Hit it reasonably hard for a minute or so. This shocks the bolt and will often break it loose. I doubt that MB used anything like Loc Tight on these bolts but over years of expanding and contracting with the engine heat will cause them to stick. As other say you can find the next size larger either metric or SAE Allen wrench and drive it in. Grind a very small chamfer on the end before you drive it in so that it doesn't roll a burr up as it goes in.
