Default piston offset question engine building advice please

so here it goes I have a set of foreged wiseco pistons that i sent to the machine shop to be balanced when i got them back he put them in a box with numbers indicating which piston is which number.... I think??? but shouldn't all the pistons weigh the same if its balanced and not matter which piston goes where???

So i went to assemble the engine yesterday Wiesco being offset pistons have a dimple thats supposd to face the front of the engine well 4 of them are wrong if i install the pistons in the cylinder number indicated on the box cylinders 5,6,7,8 the dimple faces the rear. but the valve reliefs line up

So should i just ignore the numbers on the box and install them according to the dimples or send them back to be rebalanced?????
