headers for big block A body

In the old days, I had a '71 Demon with a 383 in it. I bought it with with fender well hedders installed.....had those removed and put regular hedders on it. To get a regular hedder to fit, the drivers side hedder has to be cut and modified. Can not quite remember, but 1 for sure, maybe 2 of the tubes have to be cut out and modified with a slightly smaller piece welded back in to fit.
If you find a quality exhaust shop, I am sure they can do it.....other than modifying like this, I would look at the T.T.I. 1 3/4" chassis, as mentioned above.....or maybe a shorty hedder may fit as well.
