Port matching Pro 1 heads to Dart Intake

[Bacon104]

Is anyone finding much benefit in port matching Dart Pro 1 heads to Dart intakes? If so are you using Mr gasket 121 or on of the Ultra Seal gaskets with the same measurement to do the port matching?
Thank You

We only find it helpful over 6000 rpm. yes we use the 121 size as a baseline. We have many to work with being there are different size intake runners from 300 to 410cc.
