Default New Header Gasket Smoke

I just replaced a header gasket which was leaking. On the first startup it was smoking quite a bit. Not a colored smoke, just smoke. It even smelt a bit like metal. It stopped after about 30 seconds. The ticking I was hearing before I replaced it is gone, so I'm pretty sure it's fixed. Is this normal of a new gasket? Does it smoke as it seals the gap? Thanks!

I thought someone would have an answer to this quick! I'm assuming it could be burning off oil and dirt from my hands, or some coating they put on the gasket.

Thanks guys! I figured it was normal but I've never replaced one before. I was a little worried at first!

After a couple of cycles, it won't hurt to retorque them.
