exhaust leak
 

I took my truck into the dealer today becasue I had an exahust leak. They told me I needed new manifold gaskets. Then I get a call from them telling me that they broke 3 bolts and now they have to remove the heads to drill it out etc. These are aluminum heads so is this going to be a good fix? Has any one had this problem? I am to leave tomorrow for a 700 mile trip to NC towing a 4500 lb trailer. Help
