Here are the flow numbers on the old GT-40s along with a few of the other heads. These numbers are estimates since they used graphs in the magazine. (vl=valve lift, in=intake, ex=exhaust).

in- 60 115 160 180 190 190

in- 55 110 152 180 185 190

GT-40X
vl- .100 .200 .300 .400 .500 .600 .700

Holley (20 degree)
vl- .100 .200 .300 .400 .500 .600 .700
in- 60 125 178 222 215 216 220
ex- 40 100 130 147 150 151 149

in- 60 135 198 230 241 240 228
ex- 42 90 125 147 160 165 172

AFR 165
vl- .100 .200 .300 .400 .500 .600 .700
in- 55 119 175 215 235 247 244
ex- 50 110 150 175 183 185 187

This should give everyone an idea on the numbers they got from the flow bench.(Sorry if the numbers don't line up perfectly)
