Not really, you might want to see just where the smoke is coming from.

It might just be the paint burning off the headers.

Most headers come with cheap coatings that will burn off on first use. Black Hi-temp paint or clear anti-oxidation coatings both smell and create a little smoke/vapor.
Do make sure you are seeing header smoke, and not coolant or oil dripping from somewhere onto the header.

How long did you run it for/was it smoking for?

In my experience, yes it's normal. First your paint is curing or actually burning off, secondly I imagine they are sprayed with some sort of oil type coating to keep them from rusting in the warehouse. Oil and glue and other things tend to gather down in the collector where 4 pipes or 6 pipe turn into one. I had headers on my Jeep, when I put in the 360 the headers were pulled, cleaned and painted, during the install some old and new oil was spilled on the pipes along with a few pieces of wire loom plastic. When the 360 fired up the headers smoked for quite a while before everything turned into ash. If you don't see fire you are likely in good shape.

RIP Mike, we'll all miss you
it is recommended that a new engine be "run in" before installing a new set of headers due to the way the headers need to be "run in". Basically they are in direct opposites of each other.
The headers need to be run just until they get hot, then cooled by shutting the engine down and letting them cool naturally. then run again, cooled again, ect. until they stop smoking. then the coating will be cured enough to not burn off and let the headers start rusting.
