This in no way is meant to diminish the frustration of the OP, but just to put things into perspective.....
Granted, there have been more valve train issues than anyone would like. However, let's not ignore the fact that many are rolling along with high mileage and are still very pleased with their bike. Hence, the Chicken Little rhetoric isn't indicative of the experiences or satisfaction of K12/K13 owners as a whole. Remember, about 85% of this forums membership have not had any valve train problems. So this idea that these engines are "ticking time bombs" is hyperbole at the least. Again...have there been some problems...you betchya...but not everyone is having catostrohic failures, and in most cases aren't having valve train issues period.
OP, I would put emotions/rhetoric aside and see how the economics of this situation play out and go with whatever makes the most sense to you.
Sounds like you really like your GT, and if fixing it is within the realm of cost-effectiveness, it might be the best option if nothing else out there floats your boat.
Personally, I'd have no real concerns about an '07 GT with a new short/long block in it provided the work was done properly and backed up by a warranty.
