ya heard wrong then. yes some of them come with aluminum heads and no they dont crack. aluminum heads dissipate heat fairly quickly so it makes them more efficient and better.

@jonathanhamm88 They ALL have aluminum heads. And the problem with aluminum heads isn;t the aluminum, it's that they expand at a different rate than steel when heated, which can cause headgasket problems. But, that;s not a very common problem.
