Buying a bike with thermal/heat wraps on headers ?

[nudgedoink]

I'm planning to purchase a used fz6 with heat wraps on the headers. I'm concerned abt header damage as I've heard that wraps can do that. Is there anyway to check for damage? I doubt the owner would let me take out the wraps and see. Any other advice on whether I should purchase this bike? Or how to assess it's header condition? It's a 2006 fz6
