    You'll have to have them made most likely.

    The 6208's will work but have to be cut up. Might as well start from scratch and build them the way YOU want since you're going to have to cut 'em up anyway.

    Most of us do front end mods (M2, etc) to make the 351w fit correctly. It's just too tight between the towers for the 351w to fit with headers..or manifolds for that matter. At the very least the towers have to be "notched"

    Lastly---this subject has been covered a million times. A click on the search button would have found it.

    Just got my headers modified by SPD, www.spdexhaust.com
    and they look great. The merge/megaphone are 321 SS, so next time I will have the rest of the headers redone in SS. Should bring my 60' times down a little................we will see.

    Cleveland heads? Just guessing by the diagonal bolt holes.

    When the car ran B/SM it did have Cleveland heads, now with the 408 it has set of Roush/Yates Trick Flow mod'd R heads.
    It has some very strangely shaped exhaust ports, but the intake ports are almost the same size as Clevelands.
    We will see how the headers work????

    Here are a couple of pictures.
    You really can't see the exhaust port too well, but is flat on the bottom with a scallop on either side.
    When I get the heads back cleaned you will be able to see the shape better.

    Haven't got the engine in the car yet. Sorry but had some bad times and haven't been able to work on the car. I will be getting my second knee brace here in about 2 weeks. Then I will have both knees stable and maybe I will be able to get back at it. When I do I will get the pics of the install posted up for all to see.
