for porting or so, just to match intake runners....

How about a shop vacuum and one of those handheld wind meters?  Or if
the wind meter is too coarse a measurement tool, I seem to recall a "How
To" article in an old (10 years or so) Scientific American about making
a very low velocity wind gauge.  It involved a vertical arrangement of a
heater below and a temperature gauge above.  Supposedly it was good
enough to measure the breeze from a moth's wings.

Good idea!
Anyone ever tried one of those CPU-cooling units? They should come up with
some voltage if "abused" as a windmeter.
They are way cheaper than a good handheld windmeter.
The objective is/was to confirm equal flow in all runners, the actual
quantity being of no concern (as long as they flow equal....)
