You can get Offenhauser valve covers new from Summit Racing for about $200. P/N 5773
Rumor has it that Edelbrock will re-release their classic finned cover in the fall. It's listed in their 2005 catalog.
You can get a couple of different styles from Omix-Ada.

You can get the same ones from Quadratec.
I heard MC here had cast a couple of prototypes. When will they go into production MC? :-| :-| :mrgreen:
There was also a guy over at www.amcforums.com who had the welded sheet aluminum style for sale.
