Well the head is brand new, and we figured the smoke was white lithium grease seeping into the combustion chamber because we forgot to clean out the head. I tore apart the engine in the first place to change the piston rings because apparently they were going bad (mechanic i know smelt the exhaust when it was running and found gas on the dipstick), although there was never any black smoke, guess the rings weren't THAT bad yet. Haven't checked for coolant leaks though, and i still need to run a compression test.
