I am trying to remove a rusted exhaust manifold stud at the flange or collector. Are these pressed in studs, or can I unscrew them if so what is the rotation?

All studs and nuts are counterclockwise to remove

They are not pressed in.

The chances of getting them out without a torch to heat and cool the studs are pretty slim....you might get lucky and get them out cold..

Thanks.
I've been applying PB Blaster in an effort to break down the rust and increase my odds of getting it out. Right now the manifold is still in the car, as I'm tring to avoid taking it out to work on it.
