Okay First those tools have a really strong magnet on the end of them and what you do is once the pushrods are out put one in each pushrod hole lift it up just a little (enough for the cam to clear the lifters) then spin the wing down to the head to hole it there while you do the other 7 once that is done the pull the cam out slide new one in and undo lifters tools and voila no intake removal necessary. (that picture was ripped from
Anderson Ford Motorsport who sells them premade)
Two no it won't clear the condenser if left sitting there but with the condenser not mounted but ac hoses hooked up still, so you don't have to evacuate and recharge the ac, it moves around enough to get it out of the way just be careful with it.
