So what are you pointing out? That somebody's flow bench is way out of cal? I barely understand some of this stuff, what is the first and second set of numbers?
Intake/exhaust Flowed @28 inch depression, the standard for comparison these days.
Flow all the intake port, you usually find the one that does the number, which is typical of a lot of lesser known shops to do... port one to the target number, mirror the rest. I had been done like that a couple times wondering where the mph was... till I got my own bench and caught what was going on. **** like that attributes to as cast Eddie's making such drastic improvements over even ported factory iron, uh yeah...being one port flows 245 and the rest 218 and gping turbulent at .450...
They can look about the same and still flow 15 or so cfm apart.
Looks like a seat cut was made. Before or after initial test idk.
More to be had for sure.
