Regardless of right or wrong bearings, he is responsible for measuring all clearances. He was given $500 just to assemble it (not including any grinding to clearance).
I want to say the crank isn't true to spec judging by the slight hairline scratches in the bearings/journals already. That's just another thing he should have checked before assembly.
The #2 and I want to say #5 pistons appear to be what was causing the friction. I haven't checked the bore but it appears his honing isn't correct in those cylinders. The rings completely compress into the pistons and cause the skirts to rub the cylinder walls.
