I agree with others - the dealer needs to get you a Porsche re-manufactured motor.

Steel valves hitting aluminum pistons have most likely damaged the pistons, and probably the connecting rods, rod bearings, etc. Those bent valves probably have damaged the valve seats. Pulling the heads and replacing the valves is not an option. Engine should be pulled, completely disassembled, and every part pretty much checked. But a better, more timely solution would be a Porsche re-manufactured motor. You only had 30K miles on your original motor.

I'm really sorry this happened to you... hang in there, it can be fixed...
