Nitrous ported heads

I have read about cylinder heads being ported specific to nitrous applications. What exactly is being done that is different than a traditional CNC porting?

Usually the exhaust port is different. Depends on who does it, but usually the port bigger and the valve job is different to accommodate the power adder.

Yep, like KCS said, the work done to the exhaust port is different/spec'd for a power adder. I've never seen anything specifically done to the intake ports in regards to a "nitrous port".

Would porting for a turbo motor look any different?

I'm no porter, but I'd assume that there are things that can be done to an intake port also to make it more nitrous friendly.

A street N/A car needs properly sized ports for driveability and torque all over. On a nitrous car running WOT that's not really going to be a concern, so bigger ports that are designed for pure flow (vs. port velocity) I imagine would work well with big nitrous shots.
