well is your truck acting up or are you just wondering how to tell if they are cracked? the best way to check them is to take them off and inspect them! A machine shop should be able to tell you if you aren't sure!!!
Post with some more info!!

They do sell a kit that tests for blown head gaskets/heads. Its simple to use, and fairly accurate. It basically tests for exhaust gasses in the coolant. I get mine from the snap-on dealer, but I know I have seen simpler kits at local parts stores.
it's not acting up but when it gets in the 40's weather wise it smokes white and it scares me alittle and i really didnt want to have to pull the heads.
thanks

Yeah when i gets cold your car will make white some because the air coming out of your exhaust is hotter then the air out side!!!!
okk thanks it just scared me a little because the North American 2.9L is really bad about cracking heads and i know white smoke is a sign of water getting into your exhaust.
thanks,scott

Hi Scott,
You're right about white smoke in the exhaust being water vapor.
Often we get some condensation in the exhaust system, and it evaporates out from the heat of the exhaust gases. During the summer months it is not usually noticable, but as you noted in the winter months it is. In a perfect world, Hydrocarbons, if fully oxidized would emit nothing but CO2 (Carbon dioxide) and H2O (water) in the exhaust gases. Therefore you *may* continue to see a little steam mixed in your exhaust gases during the winter months even after the condensate evaporates out. However if YOUR engine seems to steam longer, or more, than others, then you may want to consider Jersey's suggestion.
IF your oil looks a little creamy, that is a sure sign of water in your oil.
Hope this helps.

You can learn alot by hanging in these forums. I just mentioned to one of my son's friends who is a couple of years out of high school, and working as a mechanic, that if he was interested in increaseing his diagnostic trouble shooting skills that he should participate in forums like these and see how well he can help others figure out their problems.
Don't afraid to ask questions, or to think ;-)
Welcome!
