oil burning after sbc short block rebuild

What can be the cause of my sbc 400 burning oil out of the # 5 cylinder???
It was rebuilt as a short block, while using the stock heads. The first crank up it rain perfect. It even drove perfect (city wide). After about 50 miles, I took it on the interstate. It was maybe an 45 min to an hour driver doing 70 mph @2000 rpm's. Made it to my destination with no problems. On the way back, 40 mins in the trip I noticed a change in the sound of the exhaust. Oil pressure still reading fine, water temp also. Pull at the local gas station, and its running like a train. White-ish gray smoke is slightly puffing out of the driver side pipe. Now it feels like its running off 7 cylinders, won't hold a idle in drive, and is hesitating bad. Any help on what can possible be wrong???
