Look at ZZP for a sim if you want, or just run the o2 sensor in with a spark plug non-fouler. But that looks like a good list minus the gaskets. Copper RTV is a good idea, and SSAC and Speeddaddy's are 100% identical just made by 2 different companies, and as far as we can tell there is no real quality difference.
The only thing that may be missing off of that list is bolts from the rear most header piece to the exaust mine were melted into solid pieces, and the circle gasket from the rear most piece to the cat back, mine was not included with the headers.
