What about the flow numbers from 100-600 lift on the Bowties? I couldn't find them anywhere on the net.

This is meant to compare "out-the-box" performance between them two heads. I can buy either set for same money.

The Sportman heads flow is as follows:

Lift IN EX
.100 70 49
.200 107 95
.300 176 124
.400 210 130
.500 218 138
.600 222 142
I think you might have the flow numbers for the S/R Torque head.The last set of Sportsman's heads I did flowed over 240 at .600 out of the box with a 2.02, 1.6 valve.
