engine break in issue

Holley 670 street avenger I have it jetted all the way down as low as I can go also i have oil comming out of my mufflers!!! So I dont think its gas smoke but thank you for the suggestion. The car runs great outside of the smoking thing, im thinking ( hopeing ) its stem seals. I will start there and see where it gets me. So thanks to all for the input its been a great help.
