Looks good. Are those Wisco pistons and 3SX rods? I'm doing exactly the same thing and doing the oil pump, rear seal assembly and pan this weekend.
I'm not in a hurry, too many other projects.
Did you install new oil jets? New ones cost only about $9.00 each at Mits with a discount.
How much was the balancing? My machine shop charged $285.00 and it's within 1/2 gram. Are you balancing the flywheel and clutch assembly separate from the rotating assembly?
Lay the oil pump on a flat surface and insert the bolts in the holes so they stick out above the oil pump and least 1/2 inch. Always measure the bolt hole depth too. I may be able to send a photo later in the week.
