Mine was done by a professional engine builder, as you suggested. So I'm curious to learn more about how you did it.

I did not have a proper bore guage. That is why I am stressing that it needs to be checked and double checked. I thought ordering a oem bore piston and using a stock unbored block would be OK. But it is very noisy and I am concerned about piston wall scoring or a piston skirt breaking. This is a perfect example of what my car sounds like when starting cold. My piston rings gap was checked and I am not burning any oil and the car runs great. Just very noisy. I have searched the net and it seems to be a common complaint with cp pistons.
