Very good now you just have to dress the sealing surface between the manifold & exhaust elbow. You can use a mill bastard file or a sanding block with 80 grit sandpaper. Then check the flatness with a straight edge & feeler gauges you want it to be less than .003” thickness variation. Preferably like .001”, that’s what I got with new Barr Marine parts on my 4.3 V6.
