white smoke means your burning coolant
when you put your new heads on, did you replace your head gasket and have the mating surfaces cleaned? if not, your leaking coolant into the cylinders and burning it, hence the white smoke from the exhaust.......
as for whatever is in the back? ,... its prolly just crap burning off from your previous spills.. lol... BE MORE CAREFUL ,.... whenever you do work like this.. DO NOT rush,.. make sure EVERYTHING is put back together...
Do it right the first time!
