Don't you have it when you buy all the new parts you need to do the job? I decided to upgrade my A to the new design exhaust and while I was at it add a progressive two barrel Holley. New nuts, cupped washers, gasket and exhaust port rings. All went well until I was tightening the nuts. The nut and washer are tight on the exhaust manifold and not even touching the intake. So I guess now my only out is to remove everything and take the high dollar exhaust manifold and have it milled to match the intake. Perhaps bore the nut clearance in the manifold a bit deeper. Wasted time and money caused by poor manufacturing.
