Just put exhaust manifolds on my 63 409..the gasket goes between the exhaust manifold and the heat riser. One side of the heat riser the opening is flat the other side opening has a curved opening for the exhaust donut. The donut goes on the exhaust pipe. You will notice the exhaust flange has a similar curve for the donut. Slip the exhaust flange over the other end of the exhaust pipe pull it up to the donut bolt everything up. The exhaust studs age longer on the side with the heat riser to allow for the thickness of the heat riser That is how mine went together (hope I did right)
