Never say never……… but let’s just say I’m skeptical the numbers would show a 20% increase from .500-.600 on my bench.
I also don’t think the “big number” would get too close to 350……… not that my bench is the last word in flow data.

In other words, do I think that head would equal the flow I saw from a cnc ported Victor head with a 2.15” valve @.600 lift(348cfm) on my bench?
No.

A lot of times it’s not the flowbench but the person reading the flowbench. With a digital bench I can see turbulence building a lot faster than I could on my old fluid manometer bench. So let’s say a guy wants to brag up a bad port. In a case like the “Airwolf” heads my flow numbers had crazy bounce like let’s say from 310-327 cfm. A salesman could say that head flows 327 right. Why not right because there’s probably no one looking over his back. Instead of a suck-azz port job guys will say wholly crap those heads flow GREAT.
