There are heat resistant paper gasket sheets available with permanent 250 °C (around 500 °F) durability and works too up to 400 °C (around 750 F), for a shorter time, never had a problem with them:
here in 0,5mm thickness: http://www.ebay.de/itm/Dichtungspapi...item35c015aa86
and in 2,00mm thickness: http://www.ebay.de/itm/Dichtungspapi...item4d057e0d14
also in 0,40, 0,60, 0,80, 1,00 ... mm avaiable.
If not where mentioned you might look up dealers that are specialized in tuning parts in the US.
Surly you can try to make a copper gasket, but watch out you don't have any grates / ridges left when cutting out the gasket. Getting the right thickness wil be a task.
