You can find good used heads on vortex for under $500, here is a good head with 56k on it for $350 http://forums.vwvortex.com/zerothread?id=3879090

new pistons? on a valve strike[:-] come on guys, pistons can be cleaned and polished and will be better than standard and chances are the pistons were not damaged at all but minor dings, im entering the drama squad

RE: I think my timing belt broke
Belts that have gone in high rpms have made very large dents into the pistons. Sure you can smooth out the edges to remove hotspots, but it still wont be as strong or as safe to run on a higher hp engine. In most cases it is just a very small dent (just a noticable mark) and doesnt matter. I have seen some that needed to be replaced since they were a few mm deep.

RE: I think my timing belt broke
So I went to go look at the damage... it's bad. Nice semicircle dents in the pistons and the edges are all torn up. What really worried the guy was there was cylinder wall damage around the topfrom the bent valves. There's a lot of damage to the side of the top of the pistons. I don't know if it can be repaired or not. I took a few pics:
I don't know if it's worth repairing or not... Should I just throw a rebuilt longblock in it? Or should I repair it and if it doesn't run well then run it into a tree :-/

Mystery:
Great pics. What a bummer.
Could you give specifics on how the damage was done? You were at idle? Did you try to restart the car? I'm just wondering what situation causes the most damage.

doesn't look as bad as I expected, the pistons can be cleaned up and cant see any damage to the cylinder walls though picture is not that good and poor lighting, main damage is valves and as none broke off you might get away with new valves and re-seat them,
quick edit: I don't see any damage to the cylinders because it mainly on the edge of the pistons and will polish up okonly time the cylinders are damaged is if the valves break off and that's nasty to see repairable I would say but consider a the cost of a used or refurbished cylinder head and the cost of new valves you might just be surprised at the savings and the time to put it back together, if you remove the cams you will see how many valves you need to change because the damaged ones wont go back up into their places so the cost of repair could be dramatically reduced
