Look at a set of stock pistons they blowby all the way to the oil rings.
Here is a link to look over for you as a non beleiver of using a torque plate.
CNC: I don't doubt or question you skills and knowledge on proper race engine block preparation or the value of using a torque plate when honing,
I don't even know if GM hones the blocks with a torque plate attached or not, I'd bet they do. I'll ask some one that works on the line at GM St. Catharines ( Glendale Engine Plant) next time, if they do or.....
Again not doubting the torque plate stuff - torque plate honing works... but those pics tell me that motor ran hot. (blueing on the bores) or did you blue mark the bores before honing???
The bottom end noise problem indicates multiple critical dimentional issues which required your attention.
