Lance,
Give GP headers a call in Minnesota. They just built me a set of 1 7/8" ceramic coated headers for my 427 windsor that you just finished the machine work on. My car is a Superformance but I have the TRX1 Brodix heads which standard headers do not fit. The turn around time was quick and the product looks excellent.
