All aluminum work hardens, this is normally not an issue but if the pistons have been hit you may have an issue. I have seen nuts go thru the intake and hit a valve and piston and known the engine to run another 50k miles once the valve was replaced, but I know of many that failed veryquickly with much less damage.

cylinder head

thats what im affraid of when i seen the marks on the top of the pistons from the valves but when i seen the pictures that were sent in from d2beetle,it makes me feel better about mine, because mine kind of look the same way as his and look like they got cleaned up nice.im just worried about buy a new head and then to find out after its all put back together,the connecting rod or rods are bent.also as for corrision they look really nice not much if any to speak of mostly just the marks on the piston and a little scraps at the edge of the piston but nothing that got down to the first piston ring.

If the damage to the pistons is only on the top part and mainly superficial I think you could get way with just replacing the head and hope for the best. If the sides of the piston or walls of the block are damaged then that would be another story. I would go ahead and get a used head and put it on and see. Spray a bit of seafoam spray (Deep Creep) onto toe pistons to prevent any corosion.
Good Luck and keep us posted.

You can also go and check the classifieds over at VWVortex. I don't see many heads for sale on here.
