I ABUSED the I6 in my F100 and I overheated it once, it would get milky oil with short trips, but if I left it running for 30 minutes it would boil all of the milk out of it. Then again it had over 350K on that motor, so it came with the terroritory. You might try tightenin the head bolts a few more FtLbs and squeeze the wore out headgasket a little bit more.

If it's very humid outside, it's possible for the oil to get milky (on the dipstick) due to condensation.
The more worn your engine is, the more this will likely happen.
If it burns off when the engine warms up, then it shouldn't be a problem.
Now if it's puking up milky oil around the oil fill cap, PCV valve, and the dipstick with the engine warm, then look to other problems.
Make sure the engine is timed right. Since from what it looks like it just started overheating with the changing of the distributor, a mis-timed engine can run too cool, or overheat.
