(I mean from the combustion chamber to the intake port)
It would be good to see if the 4AG head and / or your porting have an anti-reversion effect Thumbs up!

setting up a flow bench to "flow" the reverse of intended isn't excessively hard, after all, the bench is measuring reverse flow when you check exhaust flow - blows out the valves, where checking intakes the flowbench sucks through the valves. From my understanding of anti-reversion, it is most often used in headers. Adding a step up in diameter on a primary pipe for a 4AGE header @ or about 75 - 100mm from the flange is an example of using anti reversion technology.
