'69 Dart - Head Bolts

Yes. When does it smoke? If it's only in initial startup, then it's valve seals/valve guides/valve stems. In other words, a head rebuild. I've never known one to need "just" seals, but you could get lucky, I guess.
It's actually normal on startup but then after the engine "warms up" a few minutes later it starts blowing white with a blue tinge. It blows thicker on rev.
