Again, whether or not a head is too big depends on the application. In this case, the heads work, but also keep in mind that there are guys making just as much power using a smaller head. 205cc heads on a mild 347 would be too big, but with the right cam/intake they work. But on any engine you can easily get everything to work together with big parts, and end up with an engine that runs in an rpm range so high that it becomes unstreetable. You also have to consider use, what's the point of having an engine that doesn't make power under 4,000rpm if the engine spends nearly all of it's time under 4,000rpm? Same thing with going too small, what's the point of building an engine with no power past 6,000rpm if it spends nearly all it's time past 6,000rpm(ie, a race engine with too small of a head). It all gets back to the application and the build
