You may have a problem with the fuel/air mixture. Your engine may be running way too rich. The raw fuel is being dumped into the exhaust manifold and burning there. But I think you may have a burned or leaking exhaust valve or two on one side, or poor combustion due to bad wires, plugs etc.

Smoke coming out from front of intake manifold on 1990 F150 truck?
If you aren't hearing a lot of exhaust noise and you're just getting smoke, you have either an oil leak or antifreeze leak that is getting on the exhaust manifold. If you're getting oil on the manifold you have a fire hazard and should take care of the problem immediately. If you hear exhaust gas leaking around the manifold you need to replace the gasket or possibly the manifold is cracked and you need to replace the manifold.

Does a 84 f150 fwd 5.0 need a exhaust manifold gasket when replaacing manifold?
yes, most cars are not fitted with gaskets when manufactured. as you remove the exhaust manifold bolts the metal on both ends tend to warp and are not true to each other, therefore requiring a gasket to seal any potential leaks from the metal being distorted
Bank 1 oxygen sensor located were on 1999 F150 4.2?
They are located on the passenger side. Sensor1 is right past the exhaust manifold, and sensor 2 is after the cat.
