Those are Langdon's own Stovebolt cast iron headers. To my knowledge Offenhauser only makes intakes (currently).
I think the ideal production header for a street engine for the later 6s (230-292) is the Clifford shorty tube headers.
http://cliffordperformanceshop.com/catalog/52-0011_headers_street_rod_1824829.htm They are very heavy gauge steel and have quality welds. I got a set that's practically new (the original paint in still intact) for a steal of a deal through the Inliners classifieds. Clifford thinks a lot of those headers because they get 289 a set plus shipping. As if that wasn't expensive enough add in another hundred if you want them to do ceramic coating.
:rolleyes: I plan on having mine ceramic coated locally and I'll still have way less than 300 invested in mine, even withthe coating.
Stovebolts are a much better deal, in my opinion. They're well made (from what I've heard), less expensive and will outlast 5 sets of non-coated Clifford headers. Go for it!
