I don't think a dual plane manifold would make a difference on why the back 3 cylinders are lacking fuel. If spark is there and the timing order is correct, look towards the carb and how it's set up. Are the plugs even wet?
1986 CJ7, 4.2 w/4.0 head, TFI-HEI hybrid ignition, Clifford manifold w/Holley 390 w/cold air intake, OBA, 4.5" lift, Woody CV shaft and Tattons in front, 4.10 gears - lunchbox in front, Truetrac in the back, twin-sticked, blower upgrade for running topless, trying to keep it simple.
It's just a Jeep, and if you don't wheel it once in a while, it's not even that.
