Super Six install on 1974 Dart

Once I get the manifolds off I'm going to take a better look at the freeze plugs, which seem to be oozing sealant or something. It's a dark odorless fluid. I don't know what kind of sealant the machinist used when he installed the plugs. I used Permatex #2 non-hardening on the oil pan, water pump, and other places and some of it seems to be sort of melting out, so I'm thinking the freeze plugs might have the same stuff. I'm not sure if that's normal but it is disconcerting. I haven't seen any oil or water leaks...yet.
