numbers when you get em on and running. Also, one ting I would add or suggest. It appears the manifold nuts are at the last thread on the stud. I think it would be good practice to either machine the casting at each stud location to reveal 2-3 threads extending past the nut, or supply a set of longer studs with the mani's. I would probably go with longer studs to know I had new ones that wouldn't break and cut down on fab time. Great work!
