Its like 20 psi through a fire hose will give you more than 100 psi through a garden hose

its a common debate with mod motor guys . on root style blower people clame to see no gain from porting its self . but most do agree with heads work i.e. vavle job polishing ect do show gains . its not like you can hog out a 4v head.
