Missing a Few Header Bolts...
I'm using gm gaskets so that might help but it was the header install from hell..... This is such a subjective question, I think you can drive it - but your O2s will be way off and you may get some nasty exhaust in the cabin. I would not drive far!

Its a good thing your more patient than me dude. If I was you I would take those headers off and clean out the holes. Try and thread the bolts in and all that. Hopefully you can get it.
