The flow bench doesn't tell the whole story,but is pretty good start, myself I have checked 882,624 for 350's 450,416 for 305's 743 for 4.3 and by flow numbers are almost identical.
.450'' lift is highest lift went to these were junkyard heads cleaned and checked,we checked a dozen or more 882, have checked close to that many 450,416 ,have only checked a couple 624 and 4.3 heads.
165-175cfm @25'' around .400 lift
