Take the valve cover off... see if any are sticking out past their hole in the head.
If the are, use a needle nose or vice grip and spin them out.
If they aren't, grab a dremel and a cutoff wheel and grind a slot in them. Find a torch and heat AROUND the bolt shank and use a flathead to remove them. Do not heat the bolt itself, that would defeat the purpose of expanding the metal. Wipe up the burnt oil when you're done. If you still can't get them out come back and talk to us, there are still a few more options.
Tell your buddy to go to Honda and order (2) 90013-P0A-000 and (3) 90014-P08-000, who cares if he pays more at the dealer, he shouldn't have over-torqued them in the first place.
And yeah, you don't need a torque wrench for everything; the tech at the dealership isn't going to use one for every bolt, he wouldn't make any money it would take so long. Bolts that put pressure on seals/bearings, hold critical parts, engine work, etc. should be torqued.
