What’s your educated guess on capability with these heads ootb with a good combo, let’s say using one of your current cars, what do you think, ballpark, it would MPH at ootb and then after massaging? You should have more than an Educated guess for sure, what flow numbers etc are you thinking you can get them to? And how would that “likely” translate in MPH in the 1/4,

buddy of mine ran them on a typical bracket stroker motor. 264/268 Hughes flat tappet,620 ish lift, 3100 ish pound A body, 950 carb, 1 7/8 headers, 8 inch vert, hair too much gear, etc, etc…on a summer day( not good air) car went 10.50’s at 125.
He swapped on a set of airwolf heads, similar day, keeping everything else the same, so as to have a good comparison, car picked up almost 3 mph.
The convertor isnt “right” for either head, so some improvement could be made for sure, but it was a good test regards comparing those two different heads.
