Check out these nuts. (Problem solved)

cruiser said

Rusty, you are correct and I had it wrong . They were at either end of the EXHAUST manifold. Are these the only two sets of these nuts/washers on the manifolds, or are there others that I missed? Would I harm anything by simply removing the existing incorrect fasteners and installing these and torquing them to 10 ftlbs.? Finally, could you direct me to the previous discussion of this topic? Many thanks!

They are stock. Every Slant six I've ever owned had those on the ends and regular nuts on the rest of them with the triangle iron hold downs. Theyre brass .. as you can see.. which expands at different amount per degree. They bite better and hold well, and are soft yet briddle ..as to not break the very heat cycled end studs off 'quite common too'. Bummer is that didn't always work and they broke off sometimes anyways
