Freeze plug pushed out

Well got the freeze plugs swapped out. Then he fired up the engine and while it smoked a bit on initial start up. Its started pouring out white smoke from the exhaust. I am hoping it's just the assembly lube that's still burning off, did an oil change and it was assembly lube grey. Otherwise I am thinking head gasket leak. We had the heads resurfaced, new valves, guides, 3 angle grind. It had overheated severely a few times before the rebuild. Of course new gaskets, head bolts, as they are torque to yield and have to be replaced anytime they are removed. The bolts were so wedged in from warpage. I am leaning towards thinking the block deck is warped. No leaks from the heads that can be seen on the exterior of the engine. Car runs great, which is why I am really hoping it's just break in smoke. Though, when it starts up it blows a puddle of liquid onto the ground. 20191024_143812.jpg 20191024_143815.jpg 20191024_143732.jpg
