I ran Doug's 1-7/8" primary headers, 3-1/2" to the x-crossover, and 3" for the remainder including full tails. I had 2 different induction systems dynoed for it....a Q-jet/ported HO and a Holley 950/1000/TorkerII setup. The Q-jet/HO combo made 605 peak HP...and the torque peak wasn't much different from the 667, but can't remember the exact number. I was going to try a Northwind which was new at the time, but life happened and never got to it. Another thing worth mentioning was that I added a vacuum pump due to the long stroke, which solved my "oil out the dipstick under hard acceleration" issue. Never took it to the dragstrip, but ran it with a vericom on a county road one cool fall day. It showed a 10.90et at 124MPH with me and a friend in it at the time. The thing was a barge at 4080lbs...
