Did you follow the correct "burping" procedure when filling the coolant? if you havent done many miles it could just be a combination of coolant in exhaust burning off as stated above, and airlocks in the system (can be serious so make damn sure it is burped).

However i'd suggest the compression test as a matter of course and then only if the comps check out maybe just ensure it really is burped (can't stress enough GET RID of airlocks before use) and run it a while to see if the steam & coolant level dropping stops

Otherwise, if compressions are out then Houston we have a problem (these lumps are one of the most sensitive I've known to having the job done properly, dead flat head/block decks, perfectly clean from previous HG, cleaned out bolt holes & ideally new bolts lubed up before fitting & torquing to 75lb NOT 58lb, good quality gasket used etc)
