Is it the m104 engine you have in the car if so the engine would need to be raised way more than 2 inches!!
Engine must be Raised as much as possible of course being very careful not to damage anything, the subframe is in the way of getting the sump out because of the shape of the sump as you know that. I'm not very familiar with the 202s so I'm not sure of how much space you have.
I'm not sure why you would have to rotate the crank I've done plenty and never did that. Replacing a sealant has nothing to do where the position of the crankshaft.
Also if you are using a recomended MB sealant you don't need to use gasket. Just use one or the other. Hope that helps.
