I have had a lot of Stealth heads on my bench and when I test I test EVERY port on every head. The most I have ever seen was 267cfm. Start with high numbers end with high numbers and those in the know, know better.


This! ^^^

I look at it this way: I see 9 out of 10 very good head porters have results within 10 cfm of each other. Then I see one guy with results that are nearly double that of the other guys. Who is the outlier? Or, am I to believe that Dwayne and the other head guys here are a bunch of know-nothing hacks?

I had Jeff's/MCH Eddy's checked on a local bench and the numbers were within 1 cfm of each other. Trust, but always verify.
