It's one of those things that you get form sitting too long. It might go away with regular exercise and it might not. Could be a valve seal or piston ring. Sometimes the compression test won't pick that up but a leak down might. Mild rust on the cylinder walls causing some blow by, since it was leaking coolant and smoking white. If you had the head off you should've noticed the cylinder wall condition?
I'd change the oil again after a few hundred miles and check it for contaminates; sludge, metal, etc. Certainly monitor the usage.
There's additives that are supposed to fix this, but I don't recommend stuff.
You'll get more smoke if you ATF the cylinders, but should burn off.
What's the plugs look like white, grey deposits, black & sooty or clean? If they're clean/new run it a few hundred before you check. If it persists and you;re someplace with laws that don't tolerate exhaust smoke, then you're into a tear down.
