on some of the other forums there are a few K-series experts (.org and xpf) that post on HG repairs a few times. I would have a read up on what is involved and maybe go see them to get the work done.
I dont know much about the K series, but i would not have thought that piston should have been damaged with a HGF, unless it was run when overheated for a while.
I do know that if the problem is not solved and it is done on the cheap (or by a garage that does not do it quite right) then HGF can re-occur so it is worth getting it done properly.
Dont scrap it tho - if it is that costly to repair look to fitting a new engine
