Frank, Please do not take offence, but I think you're overthinking a perceived problem. Before you get all carried away, ask on here if anyone has actually destroyed the lobes on a flathead. You say you've heard of this; where is the proof? By the way, ALL flatheads run hot, everyone knows that too! Not true, but seems to be a popular misconception.

You mention keeping components as light as possible; I too agree, and incorporate that concept as much as possible with my builds.However, it is my opinion, that if you beef up the spring pressure, this is exactly the same as adding extra weight to the valve assemblies. Many pounds of weight....
I use stock valve springs; the ones that are progressively wound, and find them more than adequate up to 6000 RPM.
