2R9 ported Cylinder - How it change the Behaivior

[KANDY]

Hi All,

Got a ported cylider, Could anyone tell me how this may effect the performance. Do I lose the bottom end.
Or could not tell only by looking at like this.

looks like all they did was hack the liner up raising the cutouts a bit and nothing else except thean up the casting in the port windows maybe??  I mean, measurements of port windows is what matters. can't tell really anything from those pics. I'm not familiar with 2vo cyl dimensions but i think they are in the tech library. MY guess would be: not much difference on those from stock in regard to performance TBH

Anyone else notice the 'finish' on that bore job??
