Yes, but now the weld color will match the tube color.
Absolutely nothing to do with performance. I just wanted to finish the job and make it look nice. Very minimal leakage on the two bolt flanges. I did grind a bit based on the carbon witness marks and added a small bead next to the bolt holes to seal them up even better.
Yes, I did blend in a radius to all three ports. It's not a lot since the top of the manifold casting is only about 5/16 inch thick.
