Do these flow numbers seem right?

I've got a set of 596 heads which have been oversized to 2.02/1.6 and ported. Just got them flow tested but the numbers seem low.

Here are the numbers

I E
.100 60 52
.200 118 105
.300 164 140
.400 194 154
.500 193 159

heads check at 68cc. If that sounds right then so be it, I picked em up for cheap anyways but i expected more. These seem low?
