Real World Flow Differences 2.08"/ 1.74" Valves vs 2.14"/ 1.81" Valves " Pictures Added"

We never changed intake valve but did do the 1.88 max exhaust, picked up 3 tenths in the 1/8th. Now if it was because the seat was opened up or what but it did work. This was when everyone was pushing the 2.14-1.74 valves. (906 head)
