I wouldnt call it extremely large, but it is definitely ported a good size. Pretty similar in size to what I normally do, but shaped differently. Looks like it's definitely judge ito's porting, am I right? :D

Your primary ports look pretty good from the inside, the closing edge of the secondaries could be done a lot better. The exhaust ports are ok from what I can see in the carbon covered, blurry pictures

Yes, they are ported.

Also, use the macro setting on the camera for those up close shots.

rotary resurrection you are right + pretty impressive, can i have them ported any larger i was thinking of getting 1/2 bridge and wanted to be sure primaries are good so i only send out front + rear side housing. thanks for the help

It's nice to see that he bevels the closing edge of the intake ports, doesnt look like it on the exhaust ports. I'd recommend bevelling the closing edge of the exhaust ports, your apex seals will thank you.

Also, remember that bigger isn't always better. I definitely wouldnt go bigger on the primaries, on the secondaries there is a little room but not too much. I'd leave the intake ports alone unless you do decide to go for a bridge.

Any larger port on the secondaries and kiss your side seals good by. If you want bigger then you could do a small half bridge, but there isnt much room for that.
What you have now would be considered a large street port. I would probably just leave the porting alone.

+1; leave 'em alone or bridge another set...
