They were saying that it causes problems due to the differnt type of metals. That the two metals dont match and eventually one of the two will warp and not seal properly. Is this this true? Thanks!

Hope this helps to answer your question....Chb46 | | |

One of our VP's just got one of the Chevys with the Dura max engines and it has aluminum heads and all they could say was he's gonna have nothing but truble with it because of that. I fiqured it was just "truck driver talk" If your a truck driver you know what I mean. Thanks
