That's crazy, I've never seen one like that. I was thinking on buying this one for the Falcon. http://cgi.ebay.com/ebaymotors/FORD-144-170-200-250-ci-SIX-CYLINDER-NICKEL-HEADER_W0QQcmdZViewItemQQcategoryZ34204QQitemZ4585410356QQrdZ1QQsspagenameZWD1V
I bought a set for my Sprint back when it was new. It was long tube and looked like those but mine was one piece. I thought they were Hookers but it was over 30 years ago so I dont remember for sure.
I have dual outlet headers on my 200. Pacemaker was the name and I got them from www.fordsixparts.com. nice place to look
