SlabSide exhaust manifolds

What were used? Early cars had the little Y that paired cylinders together, and then a tubing Y into the pipes. When did they go to regular one piece manifolds or headers?

If you are referring to street model leaf spring cars, they all used the two piece exhaust manifolds going into two pipes into one. These were produced in the UK and shipped with the car to SA.
Various types of aftermarket header systems may have been installed by owners

BTW, I still haven’t found any bacon on a street 289

Just like these, Jim?

Who was the vendor? I can't imagine a big demand for them at this point???

Yep, them's the ones. I found a US foundry that will make them, but 500 pieces is the minimum order. Or China for $4.95 each.

If they go into production, I would have interest in a set.
