Simple and easy.
Intake valves need to be larger to allow more air to flow through.
Second, the intake charge just because its more cooler doesnt mean its more dense. The exhaust was compressed gasses that are now expanding and have a higher velocity and dont require such a large port to flow the same amount of volume. The expansion does most of the work.
Third we just dont know what your getting at with the whole thread. Intake valves need to be larger, yes. Both ports need to flow better, yes. All this will help.
Nothing more needs to be said about it.
