Those in the picture are a nice looking set of headers! Are those REF's? What you did with the 6114's is exactly what I plan to do. The Hooker race header I removed was the same way you mentioned of the 6114's, relative to the primaries separated and removable collectors. I have thought about separating the two front primaries on each bank with the 6114's. As I removed the race headers I attempted to take notes mentally to some how make the next "header party" a little more fun! Thanks for the pictures. Oh, by the way, are the headers in the picture for sale?
