Ah, but having a good flow does not mean having a good fill, which is where the pressure comes in........... Providing the water can fill any and all water pockets. Which is why you will see intakes plumbed to remove any chance of having pockets in the rear of the heads. Heres my plumbing on my blower intake. The rear water passages is normally blocked off from the intake. By drilling and tapping there on both sides, then running a line elsewhere, in my case to the front water jackets. A better design would be to dump the rear lines overboard or such. I might have a conflict issue between the rear and front passages being tied together. Don't know for sure, but seen it done this way many times.

BTW, you can also have a flow of 10000 gals/min, with 0 psi.
