| receive less air flow due to the fact there is a much smaller reservoir at the inlet of those runners. I would imagine that #3 and #4 actually get the most airflow as they have the largest reservoir of air to pull from. If you look at the flow properties in a steady state it will tell you a differet story - it makes it appear as though the two rear cylinders are being force fed, but then you have to take into consideration the fact that any cylinder on either bank has 240 degrees of seperation in their intake cycles - there are no two cylinders on either bank of the engine that are drawing intake air in at the same time. This is why I say that modeling flow based on steady flow conditions can make it appear that the two rearmost cylinders receive more air and the frontal cylinders get less. Fact is, the middle cylinders actually get more air. People justify that the two rear-most cylinders must run leaner, therefore hotter, which is supported by the effects we see on complession numnbers on engines with higher miles... But the reason those rearmost cylinders wear faster is due to the coolant temperature gradient from front to rear of the block - they run a lot hotter, especially #6.
