So either way one is just as important as the other. Knowing head flow is a must in getting the best effort from the camshaft.

Just knowing what RPM range you want to run isnt enough to just start gathering parts though. Knowing RPM range and desired use is very important. And sometimes the rest of the parts that you pick may not be what you think. I`ve seen a vic Jr make more power over a performer rpm when it should have been the wrong intake. The engine will tell you what it wants but these are things you`ll never know unless you use a dyno.
