Attempting to find header gaskets.

Good morning. Would anyone have a reference or a source for header gaskets for old cast iron W2 heads? I would like to try to keep the heads because they still work. However finding header gaskets is difficult. They are slightly rounder than the race head W2 gaskets on the Hughes and Mancini websites.
