If you alter the designed outflow anywhere in the system, it will also alter the oil pressure. As long as that port is open as designed, it will get the amount of oil the design intended. Ford was using the fiber gears too so they would run with less noise.

Does this mean that those of us who are running aluminum timing gears in a 8BA (I have two) should consider something like this?
