ET Performance head comparison

I was graphing out the flow numbers from ET on there heads so I could see the difference visual and thought I would share:

I also attached the excel file for those that want it.

Regards,
Justin

cool but useless in real life as the intake would need to be added to see what these would do on a motor.
Thats when you will see some of the numbers be closer together.

Looks like you had some fun doing the graph and thanks for sharing.

Why is the 215 exhaust so down compared to the others (at least they are close) with the same valve.....
