Head flow question

Mine was done on a 10" WC bench, with "conversion factor" numbers for if it "had been done" on a 28" WC bench.
Every 50 thou from 50 to .550" high, and temp reading in n out flow. I wouldn't have thought there would be that much different air temp in that short of distance in vs out of the chamber. Especially not being actually under power.
We only did cyl 4 not the whole thing.
Took longer to calibrate the machine vs itself than to flow test that 1 cylinder.
I'd like to see my results vs stock/untouched before I post what I wound up with.
I'd like to have done all 6 cylinders worth/ but that would have taken all day, and since I'm not going against NHRA specs, I'm sure it's plenty good. remember/ mine is a daily driver truck engine that will occasionally actually be used like one, not a race car.
I did see comparo sheets from a head he did for himself, which is also on a truck/ his was better than mine at some lifts, mine eked his out at other lifts.
And a comparo sheet from one he did for someone else, that blew mine away at low lifts but was real close to mine at higher lifts, like around where my cam lift maxes out. But this head that blew mine away at lower lifts, was redone for 30* intake seats.
