Check piston to bore. Even with a perfect port, if the clearance is too much it will shave down the piston skirt.
I know what you are saying, but that intake roof and floor is choppy. Perhaps it’s not it’s first rodeo. I’m sure you see the giant plating crack as well.
I managed to squeeze a .004 feeler gauge between the piston and bore. If you mean that extremely large crack looking thing, it was a hair on the cylinder.
