hi i have a 96 3500 with 120,000 mile on it i just but the new head gasket on it with 140hp injector nozzels, 100 fuel plate, and 191 delivery valves. when the truck is running it blows a steady cloud of white smoke. when u give it fuel it blows more white then a mixture of whitish grayish black smoke. runs smooth and plenty of power but i cant figure out what the white smoke is from. is it antifreeze? cracked head? cracked block?

if any one has had this problem or no what is going on can u please help?

how much timing are you running?

some 'hazing' is typical of a larger injector (especially since its likely a 155* tip), but the effect is greatly enhanced with too much or too little timing

It is stock timing what do u suggest to set it at and how hard is it to do urself?
