Our gasket is a thicker much better gasket for a much better seal to the cylinder head. This gasket fits the 1603-01 intake manifold. We also included a Carburetor gasket. A nice heavy gasket for an excellent seal to avoid vacuum leaks. 
B&B TECH TIP:  Whenever you are reusing the original intake/exhaust manifold, always put a straight edge across the ports to make sure the manifold is not warped! A warped manifold is a sure sign of a future vacuum leak. If not perfectly flat, have a machine shop mill the manifold flat. Its well worth the money!
