Very much so. As an another member says, it’s not all about flow numbers.
The most important thing a new guy to understand is where the heads starts and where it is afterwards not only in flow numbers but also what the port is doing and where as well as how the port has changed in size and shape. This also gets coupled with the valves, chamber, bore and stroke sizes and then, what the end user is looking to do and with what drivetrain in what car for whatever the purpose is.
