I just found my notes for the header that I built for Brian, and I was way off on my guess on the diameters that I originally gave you. We used ER308L 1/16" filler for tube to tube and 3/32" filler for tube to flange. 1/8" for tube to flange is OK too though.Paul- The filler rod needed is 1/16 and 1/8. 1/16 for the runners and 1/8 for the head flange. I bought WAYYY to much 1/8.. If anyone wants some 347 1/8 filler rod I have like 5 lbs of it and need to sell some to get some money back. In the mean time I am using 316 filler on the runners.
