the flow numbers are 156mph in a 3900# 17" drag radial street car in overdrive
i have never put them on a bench, didn't buy them for flow numbers, bought them for strength.
i expect them to be slightly better flowing than brand new versions of the same thing as the chambers have been cnc'd and some light work on the guides i believe. no porting

what you have what you have referenced is a set of bare castings, not complete assemblies.
per the page they need guides installed, and a valve job before they can be used. from that point on they still do not have valves, valve seals, valve springs, seats, locks, retainers, and then get the cnc job to the combustion chambers to be compared with mine.
also keep in mind these are listed as 60cc compared to mine at 67cc.
lastly the a/c is not bolted to the cylinder heads, its bolted to the block, with that mis-information in the ad i would be worried there is more mis-information.
