Actually, Fiat is trying to dis-associate themselves with ANYTHING Chrysler has had, and the PT is one such animal. Many parts are NLA for them (try finding a heater core, for instance).

My machine shop regularly does heads for these, so in that respect there should not be any issues getting parts if it is just the typical valve job. Just be sure it gets an MLS head gasket, even if it was originally equipped with a composite (it probably is an MLS anyways, or you'd have a puddle of oil everywhere the car goes by now).

The thing I always worry about with situations like this is: even if the valves were not signifigantly damaged enough to cause a compression loss right now, how much longer will it run with them ever so slightly bent before it self destructs the guides, overheats the stem, and drops the head into the cylinder and completely trashes the engine? Many multi-valve engines have valves so tiny and springs so stiff that even a slightly tweaked valve can be forced shut "well enough" to start and run, but it won't run for long.
