If its the article I'm thinking about it was in Mopar Action. They installed them in a b body with a 383. I know the Schu's are not cheap (got the cancelled check to prove it) but they fit and don't leak.
Dusterdon is right...and it used to be on Schumachers web site but now it says Hedman install omitted. I did look up that part number on Summit and they are b-body headers. I bought a set of Schumacher headers for my Duster. It took about 45 minutes to put them on. Its still in putting it back together stage.
