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.
