Excessive Oil Consumption
What is the clearance on you piston to bore fit? What is you piston ring end gap? What grit hone was used to hone your cylinders? Did you double check the machine shops work yourself. It's a good idea to just to double check their work out. That much oil sounds like the rings to me. Does she smoke oil colored (bluish colored)? Leakdown test would be a good starting point. If you didn't hone the cylinders yourself, find out what grit they were honed with. Sounds like might have been too course to seat rings good.
