Is this fixable? (Head porting.)

I guess I did not go down far enough on my test heads to really hit the water jackets on the roof near the valve.. as the below pic has happened on my good heads!

The little dimple to the left of the valve stem in the picture is where I broke through, its really small at this point as I barely have a small crack that goes through, but my camera won't focus on that point for some reason.
Is this fixable by a good shop or do I need to now find one good 5.3 head?


This is what I was using as a reference guide.. mostly taking small things from each one and doing something.
