    Those appear to be the straight dump "rod style" headers. If you plan to bid on them, make sure they'll fit. Usually this style header dumps right into the cross-member with no room for the exhaust. They were designed to be used on a car with no cross-member behind the engine mounts.
    Those are probably not Sandersons.

    I can't imagine those headers fitting in a normal Cadillac. I thought one of the ideas behind headers was to have long enough primary pipes to establish flow in one direction and scavenge the cylinders. Those look pretty stubby for that. I am considering a set of something made for BBC with some welded flange adaptors and some of that heat wrap tape to keep the noise and heat down. Free power mods are the only ones I want to use.

    Is anyone running headers? Any kind of headers. If so please share what kind and how they are performing and so forth.

    I've seen posts here where it is said that you can use headers for a Monte Carlo and weld on the Cadillac flanges. Is this true? Something like these?

    Free power mods means things that will not ruin fuel economy and/or driveability but will make the vehicle accelerate at a faster rate.
    Headers are one example. Another example is fuel injection.

    Those seem like the cheaper SSAutochrome headers offered. Not much of a header, and they are pretty much a cheap copy of the Sanderson headers, which are made to fit the Cad 500, but not in the Cadillac body.

    You're supposed to get the BBC headers for whatever body your Caddy engine is in and use the Caddy flanges. For RWD Cadillacs Hooker #2455 BBC monte carlo headers are what *should* work, although the primaries are huge on the 2455. The ones in the auction listed above will do better since the primaries are 1.75" but whether or not they'll fit is the question. Somebody try 'em out. MTS also has Deville headers but they're like $300+.

    Re: Anybody try these before?

    Is anybody running any headers? Ape? Any suggestions? Cad Company offers a couple of custom options ranging from $495.00 to $899.00 depending on what you want. Has anyone actually done the BBC swap? I would like to drop off the headers and the car and have the local shop install along with duals. Ape did you click on the second link and check out those headers?

    Shawn Gilbert (kwikcad500 on one of the other boards) is running a set of modified Chevy headers in his Deville but I'm not sure which headers he used.

    Yup I looked. No headers here. The engine swap is ready to go whenever I get a few days and the exhaust will probably not get modified yet. I have an entire exhaust which will fit anyway and that gives me a good excuse to swap another drum to drum in there too. I'm still waiting someone else out who has actually installed a set of BBC Monte Carlo headers using the Cad flanges. I really want to see if these headers have any bad manners as installed like ruining ground clearance or collectors pointing somewhere that makes it inpossible to finish the exhaust for the street properly. Headers can sometimes be real junk. No way am I paying any more than a couple hundred bux for a pair of BBC headers either. I can always stalk Ebay for someone who has run out of inspiration.

    I'm thinking it's gonna have to be custom made for whatever vehicle. That can run into some money because of labor. Unless you know a good exhaust man who is a friend. Willing to do it with you as his trusty helper and whatever beer and materials that are involved.
