Fenderwell header kits - who makes 'em?

It looks like I will have to make a set of custom headers using 2 1/4" tubing as that is what Indy sells flanges for. The D shaped ex ports on the 440-1 CNC 325 heads are 2" wide so 2" tubing with a 0.048 wall would stick out into the flow. Tubular Automotive also sells the various pieces.
