Seems like your stuck on the phrase "flowbench is lying to you" what I get from what the others are saying, that how a head operates on a flowbench is miles different then on a engine, so it only give hints of what's going on, it's not directly compatible but obviously it partly is or otherwise we wouldn't use them at all.
