Grag, just nosing around here,, I had same problem with headers glowing expecially two rear but on both sides. Understand how an stock dual plane manifold works, when back barrels are not open thus no fuel is feeding rear clyinder enuff, thus you will run lean (dual idle circuits take care of this) in addition to ,, I had a compounded issue of vacumn booster leaking, thus sucking too much air.. Your weights will be another issue. May pay to check both?
