If the smoke is slightly grey, it is oil being burnt in the cylinders, could have been there but not noticeable previously.
Working on the engine could have allowed some oil to accumulate in the cylinders and cause the smoke when engine is started. It should reduce after some running.
If it is white, it could be coolant getting into the cylinders. At the intake manifold, is there any coolant passages? If yes, coolant could be getting into the cylinders from there. That is the reason I enquired about the coolant level.
