stuck with white smoke

hey guyz man i just had an b18b1 motor re piston ringed and new seals bearings honed it and slapped it all bak in the car even had the head checked and cleaned.! start it idles fine but then white smoke just seems to steadily pour out whut should i do? also the head was used from my old block a b18a1 motor does this have anything to do with it?

if you just slapped your old head on a new block then yes, you need to have the head machined to sit perfectly level with your block, so you wont have any gaps when you seal down the head gasket.

The white smoke is water/coolant burning.
