Ive been looking for a pic like this for some time now. I wanted to know what a street port looked like compared to a stock port.

It depends on how radical you'd like to port the exhaust ports on the rotor housings.
It looks like a mild "boxy" street port.

That does look like a very mild port. There is no "standard street port", but the ones I have seen usually raise the roof of the port quite a bit. It seems like a good idea to avoid increasing overlap on turbo applications, but I think most shops still do it at least a little bit. It might be just the picture or an old rotor housing, but that port looks kind of rough.
