5.4 oil problem

I have a 200 f-250, 5 speed with a 5.4l. I took the heads off due to a miss. I put a new valve, spark plugs and inserts in it. The work was done by a professional. It's all back together. The whole top end is new. It has a new intake. During idle, it will miss all way until about 2200 RPM, but runs great. At the point the miss starts, it will start smoking blue. I towed another truck approximately 400 to 500 miles and have burnt 5 quarts of oil. Can someone tell me how to fix the miss and burning of oil?

Absent codes and a electronic problem, do a power balance test to isolate the cylinder.

Blue smoke says rings / valves at that cylinder.

Are you sure it is not cheaper to just toss in a reman long block?
