Just use your wet brick saw and take small cuts, you a can use the sides of the blade to feather the cuts although it does wear the blades out quicker. You can use an angle grinder with a diamond cup to do rough removal as well.

I wouldn't go crazy trying to contour your chimney flue....the flow is sooo slow, it will find its way out around sharp edges etc. Most important is that you have sufficient chimney flue area to accommodate the smoke...otherwise, it will come out the front.

Where in PA are you located?
