Unless I found a
heck of a deal on Ebay, then if I were you I wouldn't waste my money on
any tube header for a street engine. Just doesn't make sense. Langdon's Stovebolt cast iron headers are less than the price of two sets of the very cheapest inline 6 headers you can find anywhere - but they'll last 20 times longer!
At $259 they're about the same price as a new set of Hedman 6 cyl tube headers and
cheaper than Clifford shorty headers. I'd be getting a set for my next 6 cyl build if I hadn't gotten a barely used set of Clifford shorties for $100.
