Hi. I'm planning to port my next head. Does anyone have any head flow figures ??? I've looked at Dattoman_1000's website. It has some figures but I'd like to get a better spread of results from different sized ports.

Neil, your image shows 'before' and 'after' figures. Was the 'before' figures for a standard port with standard valves ???

Can anyone recommend a place to have a head put on a flow bench??
