I didnt take any pics of the before, but I'll see if I can find some.

ANd the best I can do at this point in time is this pic off of the the T6 racing website.



you can see in the left hand picture, the boss where the head bolt opriginally goes, and how much volume it takes up in the port in relation to the valves. It also gives you an idea of how big it was, and how it obstructed the air/fuel charge flow.

I'll keep looking, but that should help.
