I was never able to seat my intake/exhaust manifolds seated sqaurely against the head. I tried everything - even a different manifold set. Then it hit......I looked closer at the rings that go between the intake and head. They look to be home-made and of different depth. And too deep. I bet they are made from old exhaust pipe stock. I have 2 questions: 1) For test stand purposes can I run the motor without them, 2) are after market replacements available. If not I guess I will grind these down an 1/16" or so to get them to seat without creating a holiday between the manifold and the head. Thanks - Joe PS: Mike B - I had that Zenith carb rebuilt, what a difference !

There's even a set of stepped rings for fitting a 216 manifold to a 235 head, which has different manifold and head hole diameters. I'd use my lathe for fitting purposes, but a vise and a file will also work if you support the rings with a piece of dowel rod or something similar to keep from collapsing it while you file or grind the thickness down a little. Try some of the antique parts vendors who advertise here.
