I had the same problem with my '87 B2000. I thought I would just "freshen" up the head since it smoked a bit on startup. Had it rebuilt, put it all back together and it smoked WAY worse. I came to find out that by rebuilding the head, the tired piston rings couldn't keep up. So I had to tear it all the way down, hone the cylinders, and put new rings in. After that, it was perfect.
