From what I have read and was told by others, is that there is not a crossover path for water to flow from cylinder head to cylinder head(no water passage through the intake manifold). So the little lines at the front of the heads are the highest spot for steam to get trapped. This trapped steam needs to be able to go somewhere. Stock steam flow is returned to the radiator. On my C10 I did exactly the same as above with no problems.
