The stud in the center can't be easily removed so I'm hoping someone who's done this
Yes you should be able to pull the head with the manifolds still in the car. Push the intake back little with you hand and that's all you need. Get new studs and nuts for the exhaust if you really want to save time and instal the studs in the head before you put it on. Good luck!
