Offy still makes their traditional finned aluminum valve cover. There is a really terrific "Thickson" finned aluminum valve cover currently on the market, that one is finned top and sides and is pretty unusual. There were some Wayne reproductions but I think they are out of production at the moment, the OTB version, and Tome Lowe at 12bolt.com makes a nice finned cover.
In the past, Fenton made covers, and there was a CAW cover that was apparently made for commercial trucks to lessen the valve train noise. I have one of those if you want a photo. There was a fella that ran a batch of similar looking covers but that was a one time thing. There are other more rare covers that were sold over the years. Most are two bolt versions that you can run on a two bolt head (53 and earlier) or a four bolt head (54 and later) by installing the earlier rocker studs
