    Hi guys -
    I bought a set of headers that I was told were for a Buick 350 engine. I decided to take the plunge and build out a 455, so the headers are just sitting here collecting dust. I never checked fitment on the 350 (that engine was sold). Before I try to sell here I would like to make sure that the headers will indeed fit a 350 and what brand they are. I want to make sure what I am selling will really fit, so I turn to the experts. I don't see any stamps or marks on the headers themselves. any insight you can offer would be helpful. Pics below.

    They look a lot like Hooker Headers and I'd say they are A-body 350. From the spacing of the ports and the location of the bolts. On the 350, the bolt holes are above/below the ports and the center ports are closer together. On the 455 the bolt holes are more inline with the top/bottom of the ports there is more between the center ports.

    Do you have either header gasket or a manifold. It will quickly identify it as small block or big block. They look a lot alike but aren't.

    These are my 350 manifolds. They look like the same bolt spacing.

    455 has the bolt more between the ports.

    The headers for sure look to be Buick 350. They also look like Hooker headers but the Hooker headers have a badge mounted on them so they would be identifiable as Hooker. Because they don't have a Hooker badge I would say they are Doug's. They have a very similar shape. They should be for an A body. https://www.summitracing.com/parts/dou-d200/make/buick Screenshot 2024-03-27 at 6.30.34 PM.png
