Hi,
I recently had the heads reworked, on my sbc 400 they were machined ,new valve,springs etc. I put new all new gaskets,etc. prior to the heads being reinstalled to factory specs. the block was cleaned and painted. Everything was assembled the engine fires great runs extremely smooth no issues, EXCEPT I noticed when the engine ran a few mins I was seeing some white smoke from both sides of the exhaust, not a lot, not blue, not sweet smelling like antifreeze. No water in the oil plugs look new, My question is will the smoke mostly likely clear up once its ran awhile, is it condensation/ mositure from when it was apart. or do I have some other problem. as I said the engine runs smooth accelerates no skips etc no obvious signs of any other problems. Just curious.
