yep, head gasket blown, leaking coolant into your exhaust, burning it = white smoke

Oh...then it's just condensation.

It depends on how much white smoke it is.

Take off the radiator cap and see if there's oil mixed in with the coolant, dead give away for a blown HG.

you both need to do some more reading before posting. condensation WILL NOT get into the cylinders of the engine....ever! unless it leaks in from somewhere.

a cracked cylinder wall, a failed HG, or another seal would allow coolant in.

since its small i'd imagine you either got a. the wrong HG or b. you bought a one in a million faulty HG.

replace it and find the leak.

Darn its funny how you guys are talking about this, I JUST replaced my HG like 2 days ago and just put the coolant and oil change in last night and it's still smoking on mine mainly after I get done like on the highway or speeding a lil bit but not really getting on it at all, like not even letting the vtec kick in if that tells you anything

Or maybe the head gasket wasnt installed properly. Did you replace the head gasket, or did a shop do it? If the shop did it, do they guarantee their work? If you did it, did you torque down the head bolts from the inside-out? Or, if Im not mistaken, your rings could be bad too, causing you to burn oil. Check your oil level on your dipstick......remember to take it out, wipe it, put it back in, then check it.
