various brands of aftermarket finned heads..........I also think the AMT 49 Merc Coupe has a twin carb & finned head option but again cast exhaust manifolds with the block..............so I think the AMT options are the 34 Coupe and a nice set of headers on the 41 Woody kit........of course theres the Revell 32 Tudor which has a nice finned headed, twin carbed, separate headered Flathead........can't think of any others..........lol...........andyd
