Head bolt came loose?

Head bolt came loose?
Bought this 1998 Dyna Super Glide in Dec 2014. While riding...I could hear, what sounded like to me was an exhaust leak. Pulled over...and lo and behold a head bolt had come unscrewed and fallen out. Anybody ever had this happen to them? Went to the dealer to get a replacement and they tried to sell me a top end job.."just to make sure pistons etc are ok". I know the head bolts have to be torqued in a particular pattern...will I be able to get away with just replacing the bolt and torqing it down? The engine runs great...no smoking or anything so I assume nothing was damaged?
Any advice appreciated

Problem is on newer bikes, there is a torque and then a degree amount of turn to stretch bolts. Not sure about call out on your 98 or someone used an aftermarket headgasket that just calls for a torque. I would do what djl says however first. Nothing to loose. Just stay local for a while. Very possible since it came loose is someone has stripped the aluminum in the block by overtightening.

Strip down to the case, duct tape over the piston/cylinder to prevent foreign material from getting in, drill and tap for Helicoil or Time Sert. Replace stud with a new one.
