    Head gaskets don't blow 99.9% of the time.

    If its not in your oil then it's probably not the head gasket. How about your waterpump? Also check the coolant elbows make sure they aren't leaking. There's usually something else bad when the head gaskets go on these motors.

    How white of a smoke is it? Is it blueish? Is really thick white like you can't see behind you? A little white smoke is normal especially in these colder months. How long ago did you do the lim gaskets? Did you put rtv on the corners of the block when you did them?

    To answer ypur original question, it really depends on your mechanical ability and experience. Personally I think they are not bad at all. Just pay attention to detail. Clean head bolt holes.

    I second this. Definitely depends on what you've done before and stuff. I don't think they are that bad either. But like Sushamouf said, clean the bolt holes and take your time with torque specs etc.

    Head gaskets are just a bunch of bolts past the engine cover. Keep in mind that head and rocker bolts are TTY, therefore they should be replaced and not reused.

    Guys..read his other post ... he has two dead cylinders.

    I have seen a head gasket blow out between two cylinders and not effect coolant, oil or anything else. That was on a Ford though.
    I drink..so consider that when reading my posts.
