That greenish gummy stuff in there is interesting. Never seen that before. Not a surprise on the liquid gasket stuff, though it is not specified nor needed. Only the paper gasket for that top water pump housing is really needed.
Make sure you install the new thermostat with the nipple in the 12 o'clock position. Did you buy a new short-hose to the intake manifold? Those are MUCH cheaper than the M117 equivalents !!!
You should consider getting a spare lower radiator hose, if you don't have one. Though they don't fail very often, it is a very specialized hose that is specific to the .034 and .036. The last one I got and installed was August, 2019 production. It's one of those items that I don't know how much longer it will be produced. I have MB spares of the upper hose and the 90-degree thermostat housing hose.
In the 4-5 drives that I've taken in my car since I finished the top-end job, I have not seen any difference between the Behr thermostat I had previously installed, and the new Wahler unit that I installed on my car.
