One more question. I have 3 centering rings for the intake. These are stepped for adapting an earlier intake to the late 235. Problem is the intake bore is too small. The inside diameter of the centering ring is about the intake bore side. I assume there is yet another size centering ring for my manifold (Edmunds). If so, does anyone know of a source for these? The only other thought I have is to bore out the intake to accept the centering rings I have.
