I have BDR #1360 with a Rouse 427R (550 HP) with similar flange connections as you have. After reading your Post, I inspected my flange connections and discovered that one bolt on the passenger side had lost its nut. The four bolts on the driver's side and the three bolts on the passenger side are tight. So, thanks to your post. I will replace the missing nut. Others should visually inspect their header/exhaust flange bolts. Don't want to leave an exhaust system on the roadway! Good Post!
