The whole thing looks great, not just the headers. I had one of those pans Swedefish, I was scraping speed bumps with it. I had to get a moroso 7-Quart, then cut off the sump, shortened it and inch, then welded it back together. It ended up being a hemi-6 qt. pan (the hard way).
Please take a pic of your pan below the k-member after it's installed for us.
