Friend of mine had these in his shop and tossed them on his superflow 600.
Lift. Int. Ex.
.200 144 117
.300 212 167
.400 262 205
.500 289 231
.550 306 241
.600 323 248
.650 334 251
.700 336 255
This is at 28" on a 4.35 bore. Valves are 2.200x1.810 and eddy valve job. No work was done to them.
Pretty stout numbers for OOTB. Looks like Indy -1's have a new player to contend with. They are about $815 each with valves. I'd buy these before anything from Indy.
The heads also have some pretty decent cuts for pushrod clearance in the pinch area, which was a nightmare for some people using the first gen BB Victors. Probably need a .650 offset rocker like the std window Victors.
