Yeah! And once you get the allen-wrench/socket, It takes a breaker-bar, with a length of pipe on the end to free it. The block-heater I installed several years ago on a '79 300D required removing the intake/exhaust manifolds for access. My neighbor, who works at a machine-shop, cut me a short section of allen-wrench stock, that I was able to stick in the plug and put a socket on.
Soak that plug in penetrating-oil too. Some have said it's possible to crack the block trying to get it out if it's really seized.
