I'm a machinist by trade and decide to do a little porting on an extra GSR head I had and flowed it. I maybe spent two hours total working one intake port and a little blending on the combustion chamber and doing a three angle valve job. Here are my results flowing at 28"..... These numbers are for the intake

Lift. Flow
.100 100.16
.200 174.52
.300 214.65
.400 244.96
.500 261.70

Was just wondering how these number compared to some the heads you guys send out and spend money to get p and p'ed?
