Re: I would look at larger intake valves.
My personal view is unless you are going to spend the time and money to properly develop a motor (lots of testing of lots of configurations), its best to stick to stock valve sizes. Exception to this is when your stock valves are an odd size and a slightly bigger size is common and cheap as dirt.
Why I say this is that many people in the Small block V8 world would buy heads with the largest valves possible. And make unimpressive power. Often it wasn't just the valves they screwed up on, but it was a fairly major source of thier poor performing engine. The extremely large valves looked awesome on a flow bench, but when faced with a real engine, didn't do anything. Too much of the valve was shrouded by the cylinder bore and what intake charge managed to get past it, didn't flow in in a proper efficent way.
