I just replaced the spark plugs with anti seize and white smoke is coming from where the y pipe connects to the bbk headers. It also comes out the end of the tail pipes. I started trying to remove the y pipes from the headers and headers from the block but couldn't get the headers off the block so gave up and managed with them on. I've tried putting everything back together and tightening the bolts down but nothing changed. Any ideas what could be up?

Should I just rev it up for a few minutes to see if it goes away? I've let it idle a.couple of times for about 5-10 minutes but that's it.

Did it smell at all (like burning oil)? It could just be moisture. You shouldn't have a leak between the headers and the Y pipe. Need to break that connection and get the leak fixed.
