Hey guys I am posting this for a friend.

"Hey man, my teg f***ed up.. I was driving and it sputtered, back fired, threw a black cloud of smoke, and then cut off.. Now it doesnt start, It will turn, but not start, and upon cranking it, a little white smoke comes from the block/manifold area.. whats wrong??"

I think it is his head and gasket - I may be wrong?
