I wouldn't make assumptions about the margin we do or do not make on products. You simply do not have any knowledge on that matter to make such a statement.
I recommend duals because of the insurance and peace of mind they offer over a beehive when it comes to catastrophic failures, as well as for the longer life we can get from them.

you won't lose much power with too much valve spring pressure.proper valve train geometry is important,get the correct length push rod and check you swipe pattern on your valves.

Whatever you do I suggest using a dual spring, I have seen that middle spring save a dropped valve WAY to many times to ever use a behive spring. It will save you a bunch of trouble should you ever break a spring. The PRC .650 springs are perfect and cheap, alot of people use Patriot Golds too.
The PRC .675's saved my engine due to this... Invest in them
