overheated now maybe blown head gasket?
so I was in traffic and my fans quit working and my 350 got up to 250deg and now it has a faint bit of white/gray smoke coming from the pipes when I hit accelerator ....I fixed the fans and it doesn't overheat anymore but still worried about the smoke ....any ideas maybe .....valve guides, head gaskets ...or?

Are you losing any power? If not, I wouldn't worry too much about it. Keep an eye on your coolant level though and see if it changes.

Also make sure your not getting water in your oil. It'll look milky if you are.
