Low compression 340 VS high compression...
I don't have precise tools to check the compression height of the piston but I can try and see what I get.
The flat smooth areas where the orange arrows are pointing are all within .002 of each other but I admit, my tools are not NASA precision.
The center was .004 below deck but the top and bottom edges varied. Could that be due to piston rock? I don't remember exactly but I think the top was at almost zero deck ( .002 ) and the bottom was at .005. I wonder if that could just be crude manufacturing/casting ?
