Quote: Just because 28 is the defacto standard means nothing. What looks good at 10" won't work at 28" (as seen by early ported stuff when a superflow bench top was the cats buttocks).
So...if you flow something at 28" and then test it at 32" (or more) and the port doesn't keep up mathematically...you need to fix it.
It's that simple.
FWIW...the higher the test pressure the better.
As usual a lot of people put way to much into the flow numbers... we have all seen this... big flowing heads that SUCKED on the track... you can spend all sorts of time TRYING to come up with the perfect set of heads on a flow bench... but.. I've never pulled up to the line next to a flow bench.. and everyone will agree that the best dyno is the track
