Wrench size for exhaust manifold bolts

I cant locate a wrench to loosen any exhaust minifold bolt. Could it be they have rusted down or the heat through the years has changed the head size?
Anyone else had this problem?

Totally possible. You could try a 6 point box end wrench. If that doesn't work then maybe go to the next size smaller or even a metric size. If you still can't get them, they have some extractors you may be able to use. Once you get them out, be sure to replace them all.

I agree. Try a 6 point 9/16. Also, make sure the locking tabs are bent back out of the way of the bolt heads, if it's still stock.
