Not much can be gleaned from the "look" of it. It's more about the port timing and area than how routed out the intake is.

But, just from looking at it, I'd have to guess it's a relatively mild port job.

Now, get a picture from the top (with the head off) and stick a degree wheel on the flywheel and that'll be a much better indication of how aggressive the port job is.
 
I really can't say that it's much better than stock but atleast someone tried. You can't tell by looking if the exhaust has been raised & we can't see the transfers. It just doesn't appear that a great deal of time was spent so I doubt there's much too it, not bein mean. I can easily sink 6 hrs into one & still not be as happy as I'd like to be.
 
Cannot say for shure really although it's better than nothing If it were me and my money I'd at least expect them to clean up the black spots on the intake boot for a clean seal at least that's what id do. To be honest it looks like the person who did it did it in a hurry. Cause for me it's the small things that tell me a story about the person that did the work.

This^^^^^^

There's no way to tell in these pictures how much the port timing was changed, if at all. Which would have a much greater effect on overall performance than whether or not it "looks" Like a lot or little was done
